Subject: Cleanup codepage and charset definitions.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This Cl cleans up the unused defines in fx_codepage.h. The
FXFONT_CHARSET_ defines are replaced with fx_codepage defines, this
moves fx_codepage into core instead of xfa only. Static asserts are
added to verify the public/ charsets match the fx_codepage charsets.
