ANDROID: arch_topology: Add vendor hook

Add a vendor hook in the path of topology determination. This is needed
to implement Qualcomm's proprietary load tracking scheme, WALT via
vendor modules.

This change reverts commit 834285e4 (Revert "ANDROID: sched: Add vendor
hooks for update_topology") and further refactors the revert to fit in the
current mainline. Change was originally reverted due to conflicts with
upstream merges.
