Implement user-type allowlist for Settings app on handheld_system_ext allowlist XML.

Two major changes in this refactoring are
- Removing the pre installation of settings app from the non FULL SYSTEM user
- Refactoring the broader PROFILE type to granular PROFILE types where the settings package is needed.

Bug: 413301513
Test: build and install the image to verify Settings app installed or not on different types of user
Flag: EXEMPT only affecting non-released HSUM devices.
