refactor(preg): wrap the preg_* $matches maps in newtypes

The five IndexMap shapes that the preg_* functions and Preg fill in are
now distinct types generated by preg_match_map!, so a matches map no
longer interchanges with any other map of the same key and value type.

Index<usize> is kept alongside Index<&Q> because call sites such as
config_command and event_dispatcher reach for a group by its position in
the map rather than by its capture key.
