createdb: compare strategy case-insensitive

When specifying the createdb strategy, the documentation suggests valid
options are FILE_COPY and WAL_LOG, but the code does case-sensitive
comparison and accepts only "file_copy" and "wal_log" as valid.

Fixed by doing a case-insensitive comparison using pg_strcasecmp(), same
as for other string parameters nearby.

While at it, apply fmtId() to a nearby "locale_provider". This already
did the comparison in case-insensitive way, but the value would not be
double-quoted, confusing the parser and the error message.

Backpatch to 15, where the strategy was introduced.
