Fix: parse time[(p)] with time zone correctly

[georgesittas]

Fixes #2028

Bonus fix: Redshift seems to only allow specifying the precision parameter in TIMETZ / TIMESTAMPTZ when the alternative syntax is used: WITH TIME ZONE (tested). For example:

CAST(.. AS TIME[STAMP]TZ(precision)) -> syntax error
CAST(.. AS TIME[STAMP](precision) WITH TIME ZONE) -> works as expected

Thanks for knocking out all these PRs folks.

It's really going to help us as we start our port to replace sqlalchemy with sqlglot + DBAPIs inside of ibis 🚀
