Bug 1640605 - Remove IsInAnonymousSubtree / IsRootOfAnonymousSubtree. r=edgar

In favor of the NativeAnonymous versions which they forward to.

Done automatically with:

  rg -l 'IsInAnonymousSubtree' | xargs sed -i 's/IsInAnonymousSubtree/IsInNativeAnonymousSubtree/g'

And removing the function definitions afterwards.
