Main motivation is to prevent wake lock leaks, e.g. b/133175847.
Changing power.h header breaks downstream vendor code that does C
linkage to that header b/135730848. Introduce new wakelock.h header.

We use "-Wexit-time-destructors" and "-fno-c++-static-destructors" flags
to make sure that no static variables are destroyed at exit time.
We do this to avoid the race condition between process exit and use of
static vars when calling acquire/release_wake_lock().
