[troff]: Add tests of "early" formatter features.

[troff]: Add tests of early usage of formatter features that throw fatal
errors when called "too early", but for which this error handling
appears to be dead code.  Further test the `output` request in
furtherance of Savannah #64959.

* src/roff/groff/tests/backslash-exclamation-early-does-not-fail.sh:
* src/roff/groff/tests/cf-request-early-does-not-fail.sh:

Being dealt with in bug #65118.

I think I was mistaken here.  While developing unit tests, I can't actually
get anything to appear ahead of the "grout leader" ("x T ps" and so forth).

The rest is in progress.

Check a few cases:

1. plain usage
2. leading quotation mark for passage of multi-word argument(s)
3. usage very early in the document

There appears to be an undiagnosed issue with `device`.  You can invoke it
"too early", and it won't appear on the output.  This might be the case any
time the vertical drawing position is negative.  Investigate and document.

You can invoke `output` wherever you want, but this can also break the
invariant claimed in "Document parts" [sic] of groff_out(5).  So something
documentary needs to be said about that too.
