tmac/tmac.an*: support `lq`, `rq` strings
The `lq` and `rq` strings are not a groffism, but _almost_ universally
portable to man(7) renderers.
They originate in 4BSD (1980).[1] They entered Unix System V with SVR4
(1988 or 1989).[2] mandoc(1) has supported them since its inception.[3]
* tmac/tmac.an:
* tmac/tmac.antimes: Do it. Use U+201C and U+201D if the output device
is "utf", otherwise define them as `` and ''. Don't define them as
`"` because that breaks when interpolating the strings in macro
arguments.[4]
