Move CFX_Font definition to its own file and clean up
- Rename fx_ge_font.cpp to cfx_font.cpp
- Deleted unused CONTRAST_RAMP_STEP in fx_ge_text.cpp
- Move CFX_Font definitions and auxiliary methods in fx_ge_text to cfx_font
- Remove extern "C", static, and underscore prefixes in new namespace
methods in cfx_font.cpp
