This CL is a prepatory step towards moving the stack locals blacklist
from the DebugEvaluateContext to the respective {ScopeInfo} objects.

The locals blacklist is used during local debug evaluate to
decide whether a context lookup can advance the context chain
upwards, or if lookup needs to stop at the current scope.

This CL also introduces a "Recreate" static helper method, that
allows an existing ScopeInfo to be cloned, but with a locals
blacklist attached. This will be needed since blacklists are only
created on-demand during debugging.
