Fix issue 18361: [ddoc] redirect automatically highlighted text in replaceable
macros.

Basically, this is to give the user the ability to opt out of automatic
keyword highlighting in doc text, in the cases where a proliferation of
`_`s would be needed to suppress this behaviour.

The default behaviour is not changed; the default ddoc theme will still
redirect the new macros to the old DDOC_PSYMBOL, DDOC_KEYWORD,
DDOC_PARAM.
