Hand Pose anim-data churn

Where: llkeyframemotion.cpp:787-799, llhandmotion.cpp:200-201, llcharacter.cpp:252.
Cost: "Hand Pose Priority" exceeds SSO, so each frame costs a map node plus a heap string plus two frees, per avatar.
Same treatment needed: the other string keys ("LookAtPoint", "PointAtPoint", "Walk Speed", "Speed") are std::map string compares per frame.
Fix: member or enum slots on LLCharacter.
Confirmed. S.

Verify the cost (profile or timer) before and after changing it.
