Starting with Android R launched devices, debugfs cannot be mounted in
production builds. In order to avoid accidental debugfs dependencies
from creeping in during development with userdebug/eng builds, the
build flag PRODUCT_SET_DEBUGFS_RESTRICTIONS can be set by vendors to
enforce additional debugfs restrictions for userdebug/eng builds. The
same flag will be used to enable sepolicy neveallow statements to
prevent new permissions added for debugfs access.
Test: build, boot

Default to false if the property is not set.
Device init scripts will need to be adapted to restart
loc_launcher service when property change is detected.

Analysis of disassembled code in IDA revealed that the stock
libsdmcore is just writing the brightness to a custom sysfs node
in mi_display. Bind mount the real brightness node to that so it
gets written to the real node instead.

* Used by GCAM for DSP-accelerated HDR processing
* Arguably we should label /vendor/dsp/cdsp/fastrpc_shell_3 to
same_process_hal_file like Pixels, but the partition is prebuilt thus
we're unable to relabel it.
* Copy the file to writable tmpfs, setup attributes and bind mount back
to workaround the limitation.
[ghostrider-reborn]:
Allow adsp/cdsprpcd and neuralnetworks HAL to access fastrpc_shell_3
[kras edit:
1. rename some contexts as per qva/kona
2. extend to allow camera HAL and VPP service to access it as well]

The idea is to allow us to not depend on stock QTI Bluetooth HAL, as MAC
addresses fetched from NVRAM by nv_mac script will be saved as hex-encoded
files. We can decode back saved files to then the Bluetooth one be set using
persist property so it can be read by Bluetooth HAL.
This is loosely based on similar techniques used on Mi 9 and ZenFone Max Pro M2.
