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(). R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1184673002.
