Alexander Markov 9672b22099 [vm/aot/tfa] More accurate inference of results of field getters

When getting a value from a field of covariant type we can apply
field guard summary which would narrow field type using the actual
type arguments of the receiver.

This results in more accurate types returned from widely used
iterators and for-in loops.

Doesn't affect Flutter gallery size in release mode.

Fixes https://github.com/dart-lang/sdk/issues/42413
