To avoid changing the visibiliy of data types when including
hook definition headers remove header file inclusions from
the hook definition header files.
Instead, the hook definition headers should just have forward
declarations that don't require full definition.
To provide full definitions of the types for the KMI, the
headers that define the types should be included by the
source file that instantiates the hooks - normally
vendor_hooks.c.
Since the KMI is frozen, some of the inclusions are still
required to preserve the CRC associated with symbols. Keep
these inclusions under #ifdef __GENKSYMS__.

(cherry picked from commit 369de3780428a17e9afece2f5747f03619d589b6)
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.

Some hardware has a way to restore all keyslots at once that is
significantly faster than restoring each keyslot individually, as is
done by blk_ksm_reprogram_all_keys(). Add a hook
"android_rvh_ufs_reprogram_all_keys" that allows overriding the
restoration of all keyslots after UFS reset. This may sleep, so this
must be a "restricted" Android vendor hook rather than a regular one.
Note that currently this functionality can't be upstreamed, as support
for the hardware that needs it would need to be upstreamed first.

We recently noticed an issue where freezing of user space tasks is
failed due to a process being in uninterruptible sleep state.
Currently, the logging of unfrozen tasks is disabled by default.
Although it can be enabled for debugging via a adb command, it's
usually hard to reproduce the issue. So we want to add a vendor hook
to log unfrozen tasks.
pm_debug_messages enables a large amount of log output during every
suspend/resume cycle of which at most 1 line is helpful for
investigating this recurring class of battery life issues. Deploying
builds with pm_debug_messages is therefore not viable, as it
substantially shortens the temporal span of the log. The new vendor
hook will only emit logs specific to this class of problem, and only
when the problem actually manifests.

This change adds vendor hook for gic-v2 resume to allow vendor GIC
enhancement. This is inline with hook present today in irq-gic-v3.c
with one difference that vendor hooks in v2 driver do not pass entire
gic_chip_data struct to vendor module. Instead it passes the required
fields which are irq_domain and the gic dist base to know the wakeup
IRQ reason.
The newly added vendor hook can get invoked by two ways.
1. By registering with syscore ops, .resume method can invoke vendor
hook. This is applicable for cases like suspend-to-ram which
invokes syscore ops.
2. By exporting the gic_v2_resume(), the newly added vendor hook will
get invoked during the first CPU waking up from suspend-to-idle
case.
While at this move android_vh_gic_resume() to gic_v3.h as its specific
to v3 driver.
