Move all app tmpfs types to appdomain_tmpfs. These are still protected
by mls categories and DAC. TODO clean up other app tmpfs types in a
separate change.
Treble-ize tmpfs passing between graphics composer HAL and

Directory `/postinstall/apex` is used as a mount point for a tmpfs
filesystem during A/B OTA updates. APEX packages from the new system
partition are mounted ("activated") in subdirectories of
`/postinstall/apex`, so that they are available when `otapreopt` is
running.
Directory `/postinstall/apex` used to be of type `tmpfs` for SELinux
purposes. The new `postinstall_apex_mnt_dir` label is more
restrictive, and tightens permissions granted to `otapreopt_chroot`,
`otapreopt` (running as `postinstall_dexopt`), and `dex2oat`,
regarding the apexd logic recently added to `otapreopt_chroot`.
Test: A/B OTA update test (asit/dexoptota/self_full).

When TARGET_FLATTEN_APEX=true, APEX files are not packaged in *.apex
files but flattened to the system partition under /system/apex/<name>
directories. There was a bug that those flattened files are not labeled
because the per-APEX file_contexts were applied only when building
*.apex. Fixing this by converting the file_contexts files so that
/system/apex/<name> path is prepended and applying the generated
file_contexts file for system.img when TARGET_FLATTEN_APEX=true.

Test: TARGET_FLATTEN_APEX=true m
ls -alZ /system/apex/*/* shows that the files are correctly labeled

(cherry picked from commit 426ff11951)
This is being done in preparation for the migration from ashmem to
memfd. In order for tmpfs objects to be usable across the Treble
boundary, they need to be declared in public policy whereas, they're
currently all declared in private policy as part of the
tmpfs_domain() macro. Remove the type declaration from the
macro, and remove tmpfs_domain() from the init_daemon_domain() macro
to avoid having to declare the *_tmpfs types for all init launched
domains. tmpfs is mostly used by apps and the media frameworks.

* changes:
Allow `oatpreopt_chroot` to deactivate APEX packages in `/postinstall/apex`.
Allow `oatpreopt` to run `dex2oat` from the Runtime APEX.
Allow `otapreopt_chroot` to mount APEX packages using `apexd` logic.
The dynamic linker always calls access(2) on the path. Don't generate SElinux
denials since the linker does not actually access the path in case the path
does not exist or isn't accessible for the process.

selinux_denial_metadate is an concatenation of different bug maps on the
device, including vendor one. This file is only used for debugging, so
we simply move it to /vendor instead of splitting it up.
/vendor/etc/selinux/selinux_denial_metadata has vendor_configs_file
selinux type, which is logd readable.
