Build splitPermissions manually for PackageParser

Through the PackageManager#getPackageArchiveInfo API, legacy
PackageParser can be invoked before the app process's Application
is available, so instead manually build the split permissions from
the PermissionManager service directly.

Bug: 219211480

Test: manual, re-install GMS per steps from bug
