libcamera: controls: Use vendor tags for draft controls and properties

Label draft controls and properties through the "draft" vendor tag
and deprecate the existing "draft: true" mechanism. This uses the new
vendor tags mechanism to place draft controls in the same
libcamera::controls::draft namespace and provide a defined control id
range for these controls. This requires moving all draft controls from
control_ids.yaml to control_ids_draft.yaml.

One breaking change in this commit is that draft control ids also move
to the libcamera::controls::draft namespace from the existing
libcamera::controls namespace. This is desirable to avoid API breakages
when adding new libcamera controls. So, for example, the use of
controls::NOISE_REDUCTION_MODE will need to be replaced with
controls::draft::NOISE_REDUCTION_MODE.

-            bars (left-to-right) are as follows; white, yellow, cyan, green,
-            magenta, red, blue and black. Each bar should take up 1/8 of the
-            sensor pixel array width. When this is not possible, the bar size
-            should be rounded down to the nearest integer and the pattern can
-            repeat on the right side. Each bar's height must always take up the
-            full sensor pixel array height.

-          value: 3
-          description: |
-            The test pattern is similar to TestPatternModeColorBars,
-            except that each bar should start at its specified color at the top
-            and fade to gray at the bottom. Furthermore each bar is further
-            subdevided into a left and right half. The left half should have a
-            smooth gradient, and the right half should have a quantized
-            gradient. In particular, the right half's should consist of blocks
-            of the same color for 1/16th active sensor pixel array width. The
-            least significant bits in the quantized gradient should be copied
-            from the most significant bits of the smooth gradient. The height of
-            each bar should always be a multiple of 128. When this is not the
-            case, the pattern should repeat at the bottom of the image.
-        - name: TestPatternModePn9
-          value: 4
-          description: |
-            All pixel data is replaced by a pseudo-random sequence generated
-            from a PN9 512-bit sequence (typically implemented in hardware with
-            a linear feedback shift register). The generator should be reset at
-            the beginning of each frame, and thus each subsequent raw frame with
-            this test pattern should be exactly the same as the last.
-        - name: TestPatternModeCustom1
-          value: 256
-          description: |
-            The first custom test pattern. All custom patterns that are
-            available only on this camera device are at least this numeric
-            value. All of the custom test patterns will be static (that is the
-            raw image must not vary from frame to frame).

+
+  - PipelineDepth:
+      type: int32_t
+      description: |
+        Specifies the number of pipeline stages the frame went through from when
+        it was exposed to when the final completed result was available to the
+        framework. Always less than or equal to PipelineMaxDepth. Currently
+        identical to ANDROID_REQUEST_PIPELINE_DEPTH.
+
+        The typical value for this control is 3 as a frame is first exposed,
+        captured and then processed in a single pass through the ISP. Any
+        additional processing step performed after the ISP pass (in example face
+        detection, additional format conversions etc) count as an additional
+        pipeline stage.
+
+  - MaxLatency:
+      type: int32_t
+      description: |
+        The maximum number of frames that can occur after a request (different
+        than the previous) has been submitted, and before the result's state
+        becomes synchronized. A value of -1 indicates unknown latency, and 0
+        indicates per-frame control. Currently identical to
+        ANDROID_SYNC_MAX_LATENCY.
+
+  - TestPatternMode:
+      type: int32_t
+      description: |
+        Control to select the test pattern mode. Currently identical to
+        ANDROID_SENSOR_TEST_PATTERN_MODE.
+      enum:
+        - name: TestPatternModeOff
+          value: 0
+          description: |
+            No test pattern mode is used. The camera device returns frames from
+            the image sensor.
+        - name: TestPatternModeSolidColor
+          value: 1
+          description: |
+            Each pixel in [R, G_even, G_odd, B] is replaced by its respective
+            color channel provided in test pattern data.
+            \todo Add control for test pattern data.
+        - name: TestPatternModeColorBars
+          value: 2
+          description: |
+            All pixel data is replaced with an 8-bar color pattern. The vertical
+            bars (left-to-right) are as follows; white, yellow, cyan, green,
+            magenta, red, blue and black. Each bar should take up 1/8 of the
+            sensor pixel array width. When this is not possible, the bar size
+            should be rounded down to the nearest integer and the pattern can
+            repeat on the right side. Each bar's height must always take up the
+            full sensor pixel array height.
+        - name: TestPatternModeColorBarsFadeToGray
+          value: 3
+          description: |
+            The test pattern is similar to TestPatternModeColorBars,
+            except that each bar should start at its specified color at the top
+            and fade to gray at the bottom. Furthermore each bar is further
+            subdevided into a left and right half. The left half should have a
+            smooth gradient, and the right half should have a quantized
+            gradient. In particular, the right half's should consist of blocks
+            of the same color for 1/16th active sensor pixel array width. The
+            least significant bits in the quantized gradient should be copied
+            from the most significant bits of the smooth gradient. The height of
+            each bar should always be a multiple of 128. When this is not the
+            case, the pattern should repeat at the bottom of the image.
+        - name: TestPatternModePn9
+          value: 4
+          description: |
+            All pixel data is replaced by a pseudo-random sequence generated
+            from a PN9 512-bit sequence (typically implemented in hardware with
+            a linear feedback shift register). The generator should be reset at
+            the beginning of each frame, and thus each subsequent raw frame with
+            this test pattern should be exactly the same as the last.
+        - name: TestPatternModeCustom1
+          value: 256
+          description: |
+            The first custom test pattern. All custom patterns that are
+            available only on this camera device are at least this numeric
+            value. All of the custom test patterns will be static (that is the
+            raw image must not vary from frame to frame).
