[stubs] Remove the is_jsarray bit from the TransitionElementsKindStub.

[stubs] Remove the is_jsarray bit from the TransitionElementsKindStub.

There's no need to have different versions of the fairly complex
TransitionElementsKindStub just to avoid a single instance type
check at execution time (which is used to figure out the effective
length in case of JSArray objects).

Hey Igor,

Some simple cleanup (partially in preparation for TurboFan work related to
transition elements kind).
Please take a look.

Thanks,
Benedikt
