Improve glyph mapping for non-embedded CID fonts

[calixteman]

When a non-embedded CID font lacks both a glyph map and a ToUnicode entry, its CIDs are glyph IDs and PDF.js must infer an ordering. The standard-font map does not match Trebuchet MS or Windows Symbol.

Build the Trebuchet MS mapping from MacStandardGlyphOrdering plus supplemental entries, and map Windows Symbol glyph IDs by character code. Also map Adobe arrow and integral extenders from private-use code points to Unicode.

It fixes #21713.
