Revert^2 "hwui: remove FatVector"

Revert submission 10449863-revert-fatvector

Reason for revert: b/149254345

Original change (of introducing FatVector) was reverted as a stop-gap solution to fix the aforementioned bug.

The bug was caused by an ABI lock between Surface's definition (that changed with Region) and lib-imsvt prebuilt.

Enabling this change now as we have re-compiled the prebuilt with the change enabled. Doing that via a revert of the revert.
