Which issue does this PR close?

Fixes #23109.

Rationale for this change

What changes are included in this PR?

This is one approach that tries solving #23109, by allowing the SQL parser dialect to be configured at the SessionState level.

It's still a bit inconsistent, because it doesn't follow what is set at the config level (see issue), but I guess better than nothing?

Are these changes tested?

Yes.

Are there any user-facing changes?

No.
