Provides a new domain to enable secure sensitive data processing. This
allows processing of sensitive data, while enforcing necessary privacy
restrictions to prevent the egress of data via network, IPC or file
system.

Introduce isolated_app_all typeattribute to share policies between
isolated_app and future similar apps that wish to be enforced with
isolation properties.

The bufferhub daemon policy still remains, since it still needs to be
deleted. However, since the HAL no longer exists, removing policy
related to this.

tests/sepolicy_tests.py has been checking whether the property owner
attributes are mutually exclusive. This is because current policy
language can't express the following snippet:
neverallow domain {
system_property_type && vendor_property_type
}:file no_rw_file_perms;
neverallow domain {
system_property_type && vendor_property_type
}:property_service set;
This uses technical_debt.cil to workaround this.

Test: Try to compile a type having both system_property_type and
vendor_property_type

Test: Flash new system policy onto a device with vendor policy that uses
untrusted_app_visible_* attributes, and check that old and new attributes
are applied to exactly same types.

Before, it was possible to access a hwservice without declaring
that you were a client.
This introduces the following macro:
hal_attribute_hwservice_client(hal_foo, hal_foo_hwservice)
which makes sure the above implication holds using a neverallow rule.

The NeuralNetworks runtime is a library that communicates with
NeuralNetworks HIDL services and is linked by applications. To enable
the NN runtime to use these services, applications must have explicit
sepolicy permissions to find the NN services and communicate across
binder.
This CL relaxes neverallow rules for hal_neuralnetworks_*.
Because it is affecting pre-existing neverallow rules, this CL requires
a CTS rebuild.

Test: mm
Test: ran neuralnetworks vts and cts binaries

This commit marks surfaceflinger and app domain (except isolated_app)
as clients of Configstore HAL. This cleans up the policy and will make
it easier to restrict access to HwBinder services later.
Test: Play YouTube clip in YouTube app and YouTube web page in Chrome
Test: Take an HDR+ photo, a normal photo, a video, and slow motion
video in Google Camera app. Check that photos show up fine and
that videos play back with sound.

This commit marks system_server and app domains (except isolated_app)
as clients of Graphics Allocator HAL. This makes the policy cleaner
and prepares ground for restricting access to HwBinder services.
Test: Play video in YouTube app and in Google Chrome YouTube web page
Test: Using Google Camera app, take an HDR+ photo, a conventional
photo, record a video with sound and a slow motion video with
sound, then check that photos look good and videos play back
fine, including sound.

This change associates all domains which are clients of Allocator HAL
with hal_allocator_client and the, required for all HAL client
domains, halclientdomain.
This enables this commit to remove the now unnecessary hwallocator_use
macro because its binder_call(..., hal_allocator_server) is covered by
binder_call(hal_allocator_client, hal_allocator_server) added in this
commit.
Unfortunately apps, except isolated app, are clients of Allocator HAL
as well. This makes it hard to use the hal_client_domain(...,
hal_allocator) macro because it translates into "typeattribute" which
currently does not support being provided with a set of types, such as
{ appdomain -isolated_app }. As a workaround, hopefully until
typeattribute is improved, this commit expresses the necessary
association operation in CIL. private/technical_debt.cil introduced by
this commit is appended into the platform policy CIL file, thus
ensuring that the hack has effect on the final monolithic policy.
P. S. This change also removes Allocator HAL access from isolated_app.
Isolated app shouldn't have access to this HAL anyway.

Test: Google Camera records video with sound and that video is then
successfully played back with sound
Test: YouTube app plays back clips with sound
