K1: add diagnostic BUILDER_INFERENCE_STUB_RECEIVER

Browse Source 
It's reported on receivers in extension function calls with stub type,
as such calls can shadow members of finalized stub types causing
change of resolve when corresponding type argument specified explicitly

It works by checking extension receiver during call resolution parts run
That way we can easily detect if we found an extension applicable to
stub receiver and report call diagnostic for it
