ANDROID: vendor_hooks: FPSIMD save/restore by using vendor_hooks

- To use fpsimd in kernel task, vendor_hook call is needed to
  save/restore fpsimd at scheduling time.
- ANDROID_VENDOR_DATA added to thread_struct.
- Vendor_hooks is called when thread is switching for save/restore
  fpsimd states.

This patch was previously in android-mainline, but was reverted
due to conflicts in the 6.2-rc1 merge (aosp/2365029). Adding back.
