fonts: Make fast shaping determination platform-independent (#33540)

Browse source

This makes the determination of whether or not to use fast shaping
platform independent. Previously it was less stringent for Windows,
leading to using it in cases where a font had a GSUB or GPOS table --
which broke proper shaping.

In addition, the test is made platform independent and expanded to be
more complete.

Finally, comments are added indicating that "fast shaping" will be
removed.
