[devps]: Fix Savannah #67244 (2/x).
* font/devps/generate/text.map: Drop all mappings of symbolic/
mathematical/unstyled Greek special characters `*[A-Za-z]` to
PostScript glyph names. As noted above, such mappings are not
appropriate for text fonts, which (typically) have multiple styles
available.

`mc` as an alias thereof; annotate the corresponding code point as
U+00B5, not U+03BC. The micro sign (groff: \[mc]) is a styled glyph
often found in text faces. `*m` is an unstyled, but traditionally
slanted, lowercase Greek mu used overwhelmingly in mathematical or
scientific typesetting contexts. It is not appropriate for setting
the modern Greek language.
* font/devps/generate/symbol.map:
* font/devps/generate/text.map: Remove spurious mappings of groff's
`\[mc]` to PostScript's `mu`. This prevents afmtodit(1) from
resurrecting the aforementioned problem, though for unrelated reasons
we don't regenerate the font description files for grops(1) when
building groff--we should, someday. (Among other manual changes, we
added kerning pairs; see Savannah #58897.)

Yes. This the fault of the "uniglyph.cpp" files in _libgroff_, hence the
recategorization.
I've made the following change.

Hmm, yeah, good idea. I wonder if I still have my _sed_ script in the shell
history of a still-open terminal window...
[time passes]
Seems not. :-/
After my changes above, the _only_ font descriptions that contain special
character/glyph declarations matching `*[A-Za-z]` are `SS` and `S`. The
Unicode code point associations in the latter are arguably wrong. Maybe?
Unicode has a different problem to solve here. I don't recall them having a
distinct code point for **every** Greek letter, in both cases, when employed
for "technical" writing.

Since historically _afmtodit_ did not record in the generated file how it was
run (with what options, for example)[1], that sounds like an avenue to
frustration. Might be better to advise hand-editing.
[1] But it will in _groff_ 1.24.0.
