Expand Invocation FlagPolicies on expansion flags.
For SetValue and UseDefault policies on expansion flags or flags with implicitRequirements, expand the policy into policy for each of its sub-flags. For SetValue, this addresses the issue with policies on expansion flags with overridable=true not actually letting user flags overrride the expansion. For UseDefault, this formalizes the behavior where UseDefault will wipe all user-provided flags that expand from a banned expansion flag, and will allow later work to guarantee that a later policy can override the expansion policy's subflags.
Since expansion flags do not have value, break if the invocation policy uses AllowValue or DisallowValue on an expansion flag.
