Move frame-override storage from per-character to per-profile

The Character Override tab's enabled toggle and frame checkboxes now
live on each named profile (profiles[name].override) instead of being
keyed by character. This lets the tab's new profile-list dropdown pick
which profile's override to view/edit without touching which profile
is actually assigned/active for the character - selecting an entry
only changes what you're editing. Existing per-character override data
is migrated into the character's currently active profile on load.

Also style the profile dropdown with ElvUI when available, matching
the rest of the options panel.
