Upstream libcamera commit 32635054bc76e2ababd8ea2177fca1f88229541a
changed "planes" on `FrameMetadata` to be a function. Adapt
the plugin code accordingly.
To fix build warning about a variable being unused in LibCamera::stop():
[1/2] Compiling C++ object spa/plugins/libcamera/libspa-libcamera.so.p/libcamera_wrapper.cpp.o
../spa/plugins/libcamera/libcamera_wrapper.cpp: In member function ‘void LibCamera::stop()’:

The SPA plugin is including a <libcamera/buffer.h> header file, but this
got renamed to <libcamera/framebuffer.h> to match the defined class name:

Fixes#1435
Mark some structures, arrays static/const at various places.
In some cases this prevents unnecessary initialization
when a function is entered.
All in all, the text segments across all shared
libraries are reduced by about 2 KiB. However,
the total size increases by about 2 KiB as well.
libcamera is depending on libdrm in libcamera_wrapper.cpp but it was
implicitely including the header drm_fourcc.h with libcamera
file pixel_format.h
With this patch, the libcamera plugin should explicitely depends on
libdrm as it needs DRM fourcc and should not depend on multiple
inclusion from libcamera.
Add a FourCC for Motion-JPEG compressed format. This is a temporary
addition until the format gets merged in the upstream kernel.
