[ruby/prism] Introduce transparent scopes.
A transparent scope is a scope that cannot have local variables added to
it's local table. When a local is added to it's table, it instead gets
added to the first non-transparent parent scope.
This is used in for loops to ensure the correct depth for local
variables inside the body
