Adam Klein 94a71d7c45 [parser] Skipping inner funcs: accurately record NeedsHomeObject
Inner functions which called eval, and were the kind of functions
that can use `super`, were erroneously not marked as "uses_super_property",
leading to downstream crashes when the runtime tried to load the
[[HomeObject]] from them.

This patch eliminates the public Scope::uses_super_property()
API and ensures that callers always call Scope::NeedsHomeObject()
instead.

This is a minimal fix designed for easy merging; it's likely that
in the long run we should remove most mentions of "uses super property"
and replace them with "needs home object" for clarity.
