This change folds the shared_app, media_app, and release_app domains into untrusted_app, reducing the set of app domains down to just distinct domains for the fixed UID apps (e.g. system_app, bluetooth, nfc, radio), a single domain for apps signed by the platform key (platform_app), and a single domain for all other apps (untrusted_app). Thus, SELinux only distinguishes when already distinguished by a predefined Android ID (AID) or by the platform certificate (which get the signature-only Android permissions and thus may require special OS-level accesses). It is still possible to introduce specific app domains for specific apps by adding signer and package stanzas to mac_permissions.xml, but this can be done on an as-needed basis for specialized apps that require particular OS-level permissions outside the usual set. As there is now only a single platform app domains, get rid of the platformappdomain attribute and platform_app_domain() macro. We used to add mlstrustedsubject to those domains but drop this since we are not using MLS in AOSP presently; we can revisit which domains need it if/when we use MLS. Since we are dropping the shared, media, and release seinfo entries from seapp_contexts, drop them from mac_permissions.xml as well. However, we leave the keys.conf entries in case someone wants to add a signer entry in the future for specific apps signed by those keys to mac_permissions.xml.
