Subject: [PATCH] Use standard glyph mapping for non-embedded and non-composite
 Calibri fonts (issue 18208)

Given that we handle non-embedded Calibri fonts as "mapped to standard font", we really ought to be able to use the same glyph mapping as for an actual standard font.
Note that this actually improves consistency in the code, given how we already handle such fonts if they happen to be of the `CIDFontType2` type; see https://github.com/mozilla/pdf.js/blob/b47c7eca83c35b8f9ea170aa3742fc70359726c2/src/core/fonts.js#L1186-L1190
