This reverts commit 242b11e574.
The hook android_vh_pidfd_open is not used by any vendor, so remove it
to help with merge issues with future LTS releases.
If this is needed by any real user, it can easily be reverted to add it
back and then the symbol should be added to the abi list at the same
time to prevent it from being removed again later.

After 7b26719a77c4 ("ANDROID: GKI: use internal type definitions in
vendor hooks") we stopped providing a forward declaration of 'struct
uclamp_se' and instead relied on pulling its definition from
linux/sched.h. the 'uclamp_se' structure is conditionally defined based
upon CONFIG_UCLAMP_TASK therefore causing a build error to show up for
the android_rvh_uclamp_eff_get trace point.
Fix this by providing a forward declaration of 'struct uclamp_se' like
before.

When a task yields, it relinquishes the cpu and
scheduler is tasked to find another task.
However our vendor scheduler logic implementation
could return the same task leading to a loop where
the yielded task gets to run back, so add hook point
in do_sched_yield() for vendor can do some work
before task is scheduled.

A vendor hook is added in post_init_entity_util_avg before

scheduling behavior and DVFS as they want.
trace_android_rvh_new_task_stats is not a proper hook because
it is called after the task's util is attached to cfs_rq's util,
which means updating cfs_rq's sched_avg and DVFS request are done.
