Enables the debug features required an unlocked SJTAG to the section
`on property:ro.vendor.sjtag_ap_is_unlocked=true`, so they can be
enabled when 1. PD is available on non-fused device on boot, or 2. PD is
available after betterbug acquires it from the corp service.

A0 and B0 chips have different performance characteristics when it comes
to the hypervisor because B0 waits for SysMMU_SYNCs to complete during
every memory ownership transaction.
Set debug.hypervisor.metrics_tag=hwrev_a0 on PROTO1.x and EVT1.0
devices. EVT1.1 and later are B0 and benchmarks are representative of
production devices. This is only done on userdebug/eng builds.
Test: 'getprop | grep hypervisor' on A0/B0 devices

* modify dev/logbuffer_tty16 to dev/logbuffer_tty18
Bug: 213759828
Test: 1. Enable Bluetooth in P22 devices and check uart log in
android.hardware.bluetooth@1.1::IBluetoothHci.txt
2. Enable Bluetooth in P21 devices and check uart log in
android.hardware.bluetooth@1.1::IBluetoothHci.txt
3. Fake bthal ssrdump and check the coredump log.

On userdebug & eng builds, change the owner/group of SJTAG sysfs files
that need to be written to 'system', so that BetterBug is able to write
these files.
Bug: 204381544
Test: Ensure that the writable files in the following directories have
'system' as their owner & group:
/sys/devices/platform/sjtag_ap/interface/
/sys/devices/platform/sjtag_gsa/interface/
