Fork Scheduler feature flags for native-fb (#31859)

Browse Source 
#31787 introduces an experimental scheduler flag:
`enableAlwaysYieldScheduler`, which is turned off for www. There wasn't
a SchedulerFeatureFlags fork for native-fb, so the experimental change
was enabled in the Scheduler-dev build there which causes test failures
and is blocking the sync.

#31805 introduces another scheduler flag `enableRequestPaint`, which is
set as a `__VARIANT__` on www. I've set this to `true` here to preserve
the existing behavior. We can follow up with dynamic flags for native-fb
after unblocking the sync.
