Cleanup CSS parsing

This Cl removes unused CSS parsing code. The only caller of
CFDE_CSSStyleSheet::LoadeBuffer is from CXFA_TextParser which provides a static
string. So, we know there are no Media rules, Import rules, FontFace rules or
Page rules in the input style. These rules are also not allowed in inline
styles. This CL removes the supporting code.
