osi: Use CLOCK_MONOTONIC on platforms that can't wake on BT 

Some devices (such as TVs) are not wired up to be
woken by the controller. These devices might run
into unforeseen issues going to sleep with timers
armed. This commit adds a sysprop
(bluetooth.hardware.wakeup_supported) to specify
that the platform is wired up like that, and makes
all alarms on those platforms monotonic, so they
do not count up during suspend.

Bug: 343826774
Test: m -j128 com.android.btservices & QA testing
Flag: EXEMPT, behaviour controlled by sysprop
