VSE: Allow Wingdings and Symbol Fonts

This patch makes us less restrictive on the allowed types of FreeType
font character maps we allow, rather than primarily unicode-only. This
allows us to use some legacy, symbol, specialty, and proprietary fonts
like Wingdings. Note we were a little less restrictive with vfonts,
used for 3D Text Objects, so this patch primarily helps VSE.

See D12124 for details and examples.
