libcamera: framebuffer: Allocate metadata planes at construction time
The metadata planes are allocated by V4L2VideoDevice when dequeuing a
buffer. This causes the metadata planes to only be allocated after a
buffer gets dequeued, and doesn't provide any strong guarantee that
their number matches the number of FrameBuffer planes. The lack of this
invariant makes the FrameBuffer class fragile.
As a first step towards fixing this, allocate the metadata planes when
the FrameBuffer is constructed. The FrameMetadata API should be further
improved by preventing a change in the number of planes.
