feat(flags): add flag suggestions to discover searchbox

[aliu39]

Queries for feature flag keys (sorted by count) and values from discover searchbar. Suggestions are only displayed if

• dataset=ERRORS or undefined. Flags only exist on the errors dataset.
• feature-flag-autocomplete flag is enabled
• there are >0 flags in the org

As in issues stream, flag keys are wrapped w/flags[""] to escape special characters reserved by the searchbox. They're unwrapped for value queries (for suggestions), but not for the search.

Sample search in prod: 0 results for session-replay-ui = false (a flag that is 100% true everywhere). This suggests the syntax already works w/discover search backend

Closes https://github.com/getsentry/team-replay/issues/552

Error: Unable to find an element with the text: Processing message. This could be because the text is broken up by multiple elements. In this case, you can provide a function for your text matcher to make your matcher more flexible.
