[clr-interp] Add support for Vector64 and Vector128 return/argument types in interpreter stubs

[kotlarmilos]

Description

This PR adds support for handling Vector64 and Vector128 values in interpreter stubs on arm64. It implements loading and returning of these types using SIMD registers d0 and q0 according to the arm64 ABI.

Changes

• Added InterpreterStubRetVector64 and InterpreterStubRetVector128 to load return values from the interpreter frame into the appropriate reg
• Added CallJittedMethodRetVector64 and CallJittedMethodRetVector128 to load return values from native code and store them back to the interpreter return location
• Updated CallStubGenerator::GetReturnType to handle CORINFO_HFA_ELEM_VECTOR64 and CORINFO_HFA_ELEM_VECTOR128 as valid return types
