Replace GetWord_LSBFirst with FXWORD_GET_LSBFIRSTchromium/3231
The existing implementation of a LSB first word method was incorrect,
in addition it was implemented to the BMP code, but also used in the
GIF code. Thus is should be moved to a common location.
Also added in an implementation for FXWORD_GET_MSBFIRST, since the
GIF code will need this.
