For #27276
# Details
This PR adds the ability to select labels when saving or editing a query
in the UI, so that the query will only target hosts with those labels.
It follows the API design from
https://github.com/fleetdm/fleet/pull/27196, utilizing the
labels_include_any and labels_exclude_any fields. The expectation is
that when creating or updating a query, labels_include_any and
labels_exclude_any are arrays of label names, and when fetching a single
query, they are arrays of objects with a name and an id key.
Other updates in this PR:
* Removed colons from various headings on the Save Policy Modal and Edit
Policy form
* Updated the "Delete label" text
* Removed "Policy runs on all hosts with these platforms." subheading
underneath the platform selector
* TargetLabelSelector component now has `suppressTitle` flag to turn off
the "Target" title.
