tr2/lara: revert camera after extra anim unless heavy

The Lara_State_Extra_Breath function serves as a bridging animation
between an extra animation and Lara returning to normal. This change
will respect any heavy camera triggers set during the extra animation
rather than blindly resetting to chase type.

Resolves LostArtefacts#1580.
