Now that libcamera creates threads internally and doesn't rely on an
application-provided event loop, remove the thread from the Android
Camera HAL layer. The CameraProxy class becomes meaningless, remove it
and communicate directly from the CameraHalManager to the CameraDevice.

With the FrameBuffer rework completed there is no reason to keep the
camera prepared state around as buffer allocations are now decoupled
from the camera state. Remove the camera state simplifying the API.

Switch to the FrameBuffer interface where all buffers are treated as
external buffers and are allocated outside the camera. Applications
allocating buffers using libcamera are switched to use the
FrameBufferAllocator helper.
Follow-up changes to this one will finalize the transition to the new
FrameBuffer interface by removing code that is left unused after this
change.

Move the metadata retrieved when dequeuing a V4L2 buffer into a
FrameMetadata object. This is done as a step to migrate to the
FrameBuffer interface as the functions added to Buffer around
FrameMetadata match the ones in FrameBuffer.

In the FrameBuffer interface the stream will not be available from the
buffer object as the buffer might be allocated externally. The
application needs to explicitly state which stream the buffer is being
added for to the request.
Extend the addBuffer() function to get this information explicitly from
the caller.

The stream to buffer map in the requestCompleted signal is taken
directly from the request which is part of the same signal. Remove the

Add a utils::hex() function that simplifies writing hexadecimal values
to an ostream. The function handles the '0x' prefix, the field width and
the fill character automatically. Use it through the libcamera code
base, and add a test.

According to the Android camera HALv3 documentation, the request
template metadata pack should not be modified after it is returned to
the camera stack from the HAL.
Currently, the same metadata pack is used for all types of template
request, without updating the capture intent there contained to match
the requested template type, as correctly reported by the
cros_camera_test test application.
In order to avoid modifying the single request template already returned
to the camera stack in order to update the capture intent it contains,
create a map that associates a dedicated template to each supported
capture type.

The CameraProxy is constructed with a Camera instance passed through a
shared pointer. It forwards it to the CameraDevice constructor, which
takes a reference used for the sole purpose of making an internal copy
of the shared pointer. Both constructors can thus take a const reference
instead of a value or a mutable reference. This optimises the
constructors slightly.
