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.

Vendor and system components are only allowed to share files by
passing open FDs over HIDL. Ban all directory access and all file
accesses other than what can be applied to an open file:
stat/read/write/append.
This commit marks core data types as core_data_file_type and bans
access to non-core domains with an exemption for apps. A temporary
exemption is also granted to domains that currently rely on
access with TODOs and bug number for each exemption.

Test: Build and boot Marlin. Make phone call, watch youtube video.
No new denials observed.

This switches Fingerprint HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Bluetooth HAL.
Domains which are clients of Fingerprint HAL, such as system_server
domain, are granted rules targeting hal_fingerprint only when the
Fingerprint HAL runs in passthrough mode (i.e., inside the client's
process). When the HAL runs in binderized mode (i.e., in another
process/domain, with clients talking to the HAL over HwBinder IPC),
rules targeting hal_fingerprint are not granted to client domains.
Domains which offer a binderized implementation of Fingerprint HAL,
such as hal_fingerprint_default domain, are always granted rules
targeting hal_fingerprint.
NOTE: This commit also removes unnecessary allow rules from
Fingerprint HAL, such access to servicemanager (not hwservicemanager)
and access to keystore daemon over Binder IPC. Fingerprint HAL does
not use this functionality anyway and shouldn't use it either.
Test: Enable fingerprint + PIN secure lock screen, confirm it unlocks
with fingerprint or PIN
Test: Disable PIN (and thus fingerprint) secure lock screen
Test: make FingerprintDialog, install, make a fake purchase
Test: Add fingerprint_hidl_hal_test to device.mk, build & add to device,
adb shell stop,
adb shell /data/nativetest64/fingerprint_hidl_hal_test/fingerprint_hidl_hal_test -- all tests pass

hal_*_default daemons whose policy is in common/device-agnostic policy
are provided by the vendor image (see vendor/file_contexts). Thus,
their policy should also reside in the vendor image, rather than in
the system image. This means their policy should live in the vendor
subdirectory of this project.
Test: Device boots and appears to work
