[PATCH v2 4/4] apps: cam: sdl_sink: Support more single-plane formats

[Barnabás Pőcze]

With the newly introduced `SDLTexture1Plane` it is easy to handle
any single-plane format that has an SDL equivalent. So use it for
more YUV and RGB formats.

The mapping of RGB formats is not entirely straightforward because
`SDL_PIXELFORMAT_ZZZ...888...` defines a format where the order of
the components is endian dependent, while libcamera's `ZZZ...888...`
formats are derived from the matching DRM formats, and the RGB formats
in question are defined to be little-endian there. So the
endian-independent `SDL_PIXELFORMAT_{ZZZ24,ZZZZ32}` are used.
