[JS IR] Fix the instability of LoweredDeclarationSignature

A suspend stub for the abstract function
 may be created in the context of the child function.
 If on an incremental rebuild the stub is created from
 the parent context (e.g. a file with the child is not modified),
 the resulting LoweredDeclarationSignature will be different.
 It will lead to a broken cross-module reference and broken JS code.
 Therefore it is required to wrap the creation routine
 into StageController::restrictTo() explicitly.
