MSVC: Enable clang-tidy analyser

This enables the use of clang-tidy in the VS IDE.

To use it:

1 - Enable WITH_CLANG_TIDY in your cmake configuration
2 - From the Analyse pull down menu select Run Code Analysis on...

The analyser is currently not enabled by default on build
given it is quite slow and there are quite a few problems
it reports that we still need to deal with.
