Add support for more RGB and YUV formats in the SDL sink.

changes in v5:
  * conditionally use the platform-independent "X" variants
    of pixelformats as they first appeared in SDL 2.29.1

changes in v4:
  * separate format mapping from texture creation

changes in v3:
  * move SDLTexture1Plane implementation from header
  * add copyright notice

changes in v2:
  * support more formats, not just RGB888, BGR888
  * don't specify area to be updated explicitly when calling `SDL_Update{NV,}Texture()`

v4: https://patchwork.libcamera.org/cover/23301/
v3: https://patchwork.libcamera.org/cover/23267/
v2: https://patchwork.libcamera.org/cover/23262/
v1: https://patchwork.libcamera.org/cover/23196/
