Rename enum labels of PG_Locale_Strategy
PG_REGEX_BUILTIN was added in
f69319f2f1fb but it did not follow the
same pattern as the previous labels, i.e. PG_LOCALE_*. In addition to
this, the two libc strategies did not include in the name that they were
related to this library.
The enum labels are renamed as PG_STRATEGY_type[_subtype] to make the
code clearer, in accordance to the library and the functions they rely
on.
