Merge to XFA: Remove unneeded checks in CPDF_DocPageData::GetFontFileStreamAcc().
The input cannot be null. Same for CPDF_Document::LoadFontFile(). Also set the contract for CPDF_Document::LoadFont() and adjust callers accordingly. Also remove unused CPDF_Document::FindFont().

(cherry picked from commit 1972b16849fedfda675eacd5c8594b54dbd1264d) Review URL: https://codereview.chromium.org/1181393002.
