Add support for parenthesized parameters in frontend query parser

[lguychard]

Fixes #11655

Adds naive parsing of opening & closing parentheses (no grouping / paren matching), to avoid showing squiggles on queries like r:a (f:b and c), where we previously interpreted (f:b as a single literal and suggested quoting it because it contained a colon.

Stamping. I was surprised at the 400LOC but then saw it's mostly test data :P Thank you so much.
