Unit tooltips title the unit with its PvP name, as 1.12.1 does (#802)

A unit tooltip's title read the bare name where 1.12.1 decorates it.

The tooltip calls the name builder `0x609370` itself (`0x52a1ab`, or `0x52a1db` when there is no second part) with the decoration flag a literal `1`, the same call `UnitPVPName` makes, so no CVar gates it. With the flag on, a ranked player reads `UNIT_PVP_NAME` of the gendered `PVP_RANK_<rank>_<team>` and the name, a city protector's `PVP_MEDAL<n>` follows on a second line (`0x6093ef`), and a civilian kill (`0x612550`) reads the `PVP_RANK_CIVILIAN` prefix (`0x609461`).

The title now runs the builder `UnitPVPName` already uses. The test covers rank, gender, medal, civilian, an unranked player and a creature; an on-demand `ui-tooltip-rank` capture shows a ranked player's tooltip.

Fixes #794
