76aab82cb3 Move domain_deprecated into private policy
This attribute is being actively removed from policy. Since
attributes are not being versioned, partners must not be able to
access and use this attribute. Move it from private and verify in
the logs that rild and tee are not using these permissions.

Bug: 38316109
Test: build and boot Marlin
Test: Verify that rild and tee are not being granted any of these
      permissions.

2ee66e7d14 sepolicy: make exec_types in /vendor a subset of vendor_file_type
We install all default hal implementations in /vendor/bin/hw along with
a few domains that are defined in vendor policy and installed in
/vendor. These files MUST be a subset of the global 'vendor_file_type'
which is used to address *all files installed in /vendor* throughout the
policy.

645abeaded tee no longer violates the socket comms ban
SELinux policy no longer has allow rules which permit core/non-vendor
domains to communicate with tee domain over sockets. This commit thus
removes tee from the list of temporary exceptions for the socket
communications prohibition.

304d653637 Move TEE rules to vendor image
"tee" domain is a vendor domain. Hence its rules should live on the
vendor image.

What's left as public API is that:
1. tee domain exists and that it is permitted to sys_rawio capability,
2. tee_device type exists and apps are not permitted to access
   character devices labeled tee_device.

If you were relying on system/sepolicy automatically labeling
/dev/tf_driver as tee_device or labeling /system/bin/tf_daemon as
tee_exec, then you need to add these rules to your device-specific
file_contexts.
