Cleaning up naming of GIF files/classes/variables

Moved everything from core/fxcodec/lgif to core/fxcodec/gif
Converted CGifContext -> CFX_GifContext
Removed _ptr suffixes from CXF_GifContext
Movef fx_gif.* -> cfx_gif.*
Renamed structs in cfx_gif.h
Renamed members of CFX_GifImage
Renamed members of CFX_GifContext
Renamed CFX_LZWDecoder -> CFX_LZWDecompressor
