Fix MSVC warning in CompilerInvocation.cpp (#152809)

Building Clang using MSVC was resulting in the following warning:

```
tuple(791): warning C4018: '<': signed/unsigned mismatch
```

I traced this to CompilerInvocation.cpp where it was creating a
`std::tuple` to compare version numbers.

This change adds an explicit type for the `tuple` created from the
version macros to match the type of the variables, and uses the `tuple`
constructor instead of `tie` since the integers are smaller than a
reference to the integers.
