This reverts commit eb994f2728.
The hooks android_rvh_attach_entity_load_avg,
android_rvh_detach_entity_load_avg, android_rvh_update_load_avg,
android_rvh_remove_entity_load_avg, and android_rvh_update_blocked_fair
are not used by any vendor, so remove it to help with merge issues with
future LTS releases.
If they are needed by any real user, it can easily be reverted to add
them back and then the symbols should be added to the abi list at the
same time to prevent it from being removed again later.

Change how vendor hooks are instantiated to promote
more complete structure definition in the ABI XML
description without complicating hook definition for
partners.
We don't want to force partners to include all
headers as part of the hook definition in include/trace/hooks/
since that causes extra headers to be included in
source files that runs the risk of changing visibility
resulting in CRC changes to KMI symbols. Instead continue
the practice of using forward declarations in the hook
header files.
Instead of instantiating hook tracepoints globally in
drivers/android/vendor_hooks.c, use subsystem-specific
vendor_hooks.c. This avoids namespace collisions between
internal header files and limits the exposure to the internal
headers to the instantiation, not the call sites.
In this patch, all of the scheduler related hooks are
instantiated in kernel/sched/vendor_hooks.c which can
cleanly include scheduler-related header files to
provide full type visibility.
Since this is being done on a KMI frozen branch, there
are some __GENKSYMS__ tricks needed to preserve the
existing CRC as we increase the number of fully typed
structs. These tricks won't be needed when this is
introduced on a non-KMI-frozen branch.
With this patch, the number of undefined types was
reduced from 108 to 68.
