Adds support for fuseblk binaries.

This is a rather large, single change to the SEPolicies, as fuseblk
required multiple new domains. The goal is to allow any fuseblk
drivers to also use the same sepolicy.

Note the compartmentalized domain for sys_admin and mount/unmount
permissions.

Bug: 254407246

Test: Extensive testing with an ADT-4 and NTFS USB drives.
