LibGfx: Rename RGBA32 => ARGB32
The ARGB32 typedef is used for 32-bit #AARRGGBB quadruplets. As such, the name RGBA32 was misleading, so let's call it ARGB32 instead. Since endianness is a thing, let's not encode any assumptions about byte order in the name of this type. ARGB32 is basically a "machine word" of color.
