Reviewed by Brent Fulgham.

Originally the Safe Font Parser was intended to be used
as a fallback parser for when there was a restriction
(imposed by lockdown mode) on dowloading font binaries
and a binary was not listed as trusted.

However, after [1], if we are restricted to download font
binaries and a binary is not trusted the font is denied
and we won't fallback. Therefore, the Safe Font Parser
is no longer used as a fallback parser.

The current patch renames the DownloadableBinaryFontTrustedTypes
value and update comments accordingly.
