Add address_sanitizer option for MSVC builds

[lederernc]

This adds the ability to build clipper2 with address_sanitizer in MSVC

This kind of reads like a very verbose MSVC-only alternative to https://github.com/arsenm/sanitizers-cmake

This is basically a copy of what we use internally for our MSVC builds. I did not bother to copy over what we do for linux (for ASAN, UBSAN, and TSAN). We do not develop for Mac so I got nothing there.

I looked at your suggestion and didn't like what I saw there (for our internal stuff). It doesn't look like it would work on MSVC.

I eagerly await your PR providing the same capabilities, but better. Better is better.

Not planning to add anything here, so I'm not going to block any attempts at merging this, just offering some basic suggestions.
