This patch:
* allows for heap and perf profiling of all processes on the system
(minus undumpable and otherwise incompatible domains). For apps, the
rest of the platform will still perform checks based on
profileable/debuggable manifest flags. For native processes, the
profilers will check that the process runs as an allowlisted UID.
* allows for all apps (=appdomain) to act as perfetto tracing data
writers (=perfetto_producer) for the ART java heap graph plugin
(perfetto_hprof).
* allows for system_server to act a perfetto_producer for java heap
graphs.

We want to more closely monitor the system properties that the
sdk_sandbox has access to.

Next attempt at rolling forward aosp/2200430. It appears the
first-stage-init did not create the /dev/selinux folder on GSI
instances, resulting in breakages when selinux.cpp tries to copy files
to that folder.

Revert "Add seamendc tests for sdk_sandbox in apex sepolicy"
Revert submission 2201484-sdk_sandbox
Note: this is not a clean revert, I kept the changes in aosp/2199179
and the changes to system/sepolicy/Android.mk. Those changes are already
part of internal, I do not want to put those files out of sync again.

Third attempt to roll-forward the apex_sepolicy changes from
aosp/2179294 and aosp/2170746.
I was finally able to figure out the likely root cause of the test
breakages in internal b/243971667. The related CL aosp/2199179 is making
the apex_sepolicy files mandatory for all AOSP builds.
Without the apex_sepolicy files, mixed GSI builds in internal using AOSP
as base would not implement the sdk_sandbox rules, causing breakages for
the SdkSandbox components.

This is a roll-forward of a small chunk of aosp/2170746.
The previous CL was causing test breakages (b/240731742, b/240462388,
b/240463116).
This CL is smaller than the previous one, it only moves allow rules from
the platform policy to the apex policy (I believe the error was caused
by typeattribute rules). I also ran the closest approximation I could
find to the breaking environment, and it appears the tests are passing

To perform sdk sandbox data isolation, the zygote gets the selinux label
of SDK sandbox storage (e.g. /data/misc_{ce,de}/<user-id>/sdksandbox)
before tmpfs is mounted onto /data/misc_{ce,de} (or other volumes). It
relabels it back once bind mounting of required sandbox data is done.
This change allows for the zygote to perform these operations.

Currently, app process can freely execute path at
`/data/misc_ce/0/sdksandbox/<package-name>` since it's labeled as system
file. They can't read or write, but use 403/404
error to figure out if an app is installed or not.
By changing the selinux label of the parent directory:
`/data/misc_ce/0/sdksandbox`, we can restrict app process from executing
inside the directory and avoid the privacy leak.
Sandbox process should only have "search" permission on the new label so
that it can pass through it to its data directory located in
`/data/misc_ce/0/sdksandbox/<package-name>/<per-sdk-dir>`.
