Christopher Di Bella b28e899a8c refactors PerformCppOverloadResolution to take CppOverloadSet (#6829) ...

`PerformCppOverloadResolution` computes an overload set from a
`CppOverloadSetId`, but the compiler sometimes needs to synthesise a
local overload set for witnesses. `PerformCppOverloadResolution` now
requires callers to produce the `CppOverloadSet` to address this
problem.
