libcamera: debayer_cpu: Add 32bits/aligned output formats

Browse Source 
In order to be more compatible with modern hardware and APIs. This
notably allows GL implementations to directly import the buffers more
often and seems to be required for Wayland.

Further more, as we already enforce a 8 byte stride, these formats work
better for clients that don't support padding - such as libwebrtc at the
time of writing.

Tested devices:
 - Librem5
 - PinePhone
 - Thinkpad X13s
