Spmi source code cleaning (dotnet/coreclr#12378)

Spmi source code cleaning (dotnet/coreclr#12378)

* fix pointer names in CORINFO_RESOLVED_TOKENin

* Remove exceptionCode from Agnostic_CORINFO_RESOLVED_TOKENout

The target if to do Agnostic_CORINFO_RESOLVED_TOKEN =
Agnostic_CORINFO_RESOLVED_TOKENin + Agnostic_CORINFO_RESOLVED_TOKENout

* Agnostic_CORINFO_RESOLVED_TOKEN = Agnostic_CORINFO_RESOLVED_TOKENin + Agnostic_CORINFO_RESOLVED_TOKENout

* spmi cleaning for ResolvedToken.

It is only the first part of changes. I am trying to delete as many code
as I can, because for now it is bad pain to make changes in this files.
