The two overloads of `find()` and `at()` have the same behaviour
regardless of the argument type: `unsigned int` or `const ControlId *`.
However, `count()` is not so because `count(unsigned int)` only checks
the `ControlIdMap`, and it does not check if the given id is actually
present in the map storing the `ControlInfo` objects.
So `count()` returns 1 for every control id that is present in the
associated `ControlIdMap` regardless of whether there is an actual
entry for the `ControlId` associated with the given numeric id.
Fix that by simply using `find()` to determine the return value.

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.
