Move ParameterInfo.cs and Assembly.cs to shared partition. (dotnet/coreclr#10270)

Move ParameterInfo.cs and Assembly.cs to shared partition. (dotnet/coreclr#10270)

* Clone the files.

* Split the members between shared and nonshared files.

* Replaced ParameterInfo with CoreRt text member by member.

* Replaced Module.cs with CoreRt text member by member.

* Remove dead filter code.

* Replaced Assembly.cs with CoreRt text member by member.

* Transplanted CoreRt files.

This is a reordering without any other changes.
Verified by sorting the old and new files and
diffing.

* Migrated ParameterInfo.cs and Assembly.cs to shared directory.

Leaving Module.cs in place for now as one line is going to
have to change over in CoreRt land.

 ModuleHandle ModuleHandle => new ModuleHandle(this);

* Cleanup.

* Move the final internal methods to RuntimeParameterInfo.
