c39192ba64 Backends: SDL_Renderer: Fix texture atlas format on big-endian hardware (#4927) 
SDL_PIXELFORMAT_RGBA32 is intended for byte arrays where the channels
are specifically in the RGBA order. However, this is not what
GetTexDataAsRGBA32 does: rather, it constructs an array where each
pixel is an unsigned int in ABGR order. On little-endian platforms,
this does indeed result in an RGBA byte order, however, on big-endian
platforms, this results in an ABGR byte order, which does not match
the PIXELFORMAT enum.

What should be used is the SDL_PIXELFORMAT_ABGR8888 enum, which
specifies that the pixels are in native-endian ABGR, which they are.
