[canvaskit] Remove support for T1 fonts and reduce code size
We were previously building FreeType2 with the psnames module,
which included large tables of glyphnames [1]. These were only
used in code related to PDF (and only when outputting Type 1
fonts, which is very rare).
Even though the PDF backend isn't in CanvasKit, the compiler
couldn't throw away these massive tables (about 80k in all)
of strings. Since these tables were only used for T1 fonts,
it made sense to tell FreeType not to include the rest of the
T1 related code, which saved about 55k more.
If, one day, we add in support for the PDF backend to CanvasKit,
SK_PDF_DO_NOT_SUPPORT_TYPE_1_FONTS is likely something we'll
want to define.
The roll-freetype.sh is inspired by a script of the same name
in the Chromium repo and aids in the updating of freetype
and our forked config files.
