Use Optional to determine if appearance stream as fontchromium/3388
This CL changes the CPDF_DefaultAppearance code to remove the HasFont
method and change GetFont to return an Optional. This forces all the
call sites to verify a font was returned correctly and removes the need
for the duplicate appearance stream parsing.
