Update Phabricator to use intermediate tokens from the query compiler

Summary:
Depends on D17669. Ref T12137. Ref T12003. Ref T2632. Ref T7860.

Converts Phabricator to the new parse + compile workflow with intermediate tokens.

Also fixes a bug where searches for cat" or similar (unmatched quotes) wouldn't produce a nice exception.

Test Plan:

• Fulltext searched.
• Fulltext searched in Conpherence.
• Fulltext searched with bad syntax.
