[dartdevc] fix #34596, hot restart can now clear field & cache state

This adds a method to the internal SDK runtime library that can be
called to clear state when a hot restart is desired.

This also refactors some of the logic around ignoring type errors,
as we need to ensure we can clear those caches. Also I noticed a bug
where the result of isSubtypeOf was assumed to be non-null, but this
was not the case. The new structure should make this more clear.

(Note: I think we may be able to remove a lot of the code for ignoring
type errors soon.)
