USD: speed up large USD imports by not rebuilding material name map for each object
Previous code was rebuilding "name to material" map for each object
being imported. Which means O(N*M) complexity (N=object count,
M=material count). There was already a TODO comment suggesting that
a single map that's maintained for the whole import would be enough.
This commit does exactly that.
While importing Moana USD scene (260k objects, 18k materials) this
saves about 6 minutes of import time.
