dundargoc 397b92e02d build: enable ASAN for MSVC
It is enabled with ENABLE_ASAN_UBSAN like other compilers. Technically
it only enables ASAN as UBSAN is not available, meaning to make the
variable names fully correct we'd need to separate it into two checks:
ENABLE_ASAN and ENABLE_UBSAN, but the convenience of combining them into
the same flag outweighs the theoretical correctness.

Also note in CONTRIBUTING.md that debug builds in ASAN is not supported.
Technically it is the debug runtime that is not supported, which cmake
automatically enables when using the debug build type. However, neovim
can't be built with debug builds without linking to the debug runtime
since the third party libraries has likely been linked to the debug
runtime if it was built with debug build type. This technicality is
likely uninteresting to the potential developer and it's easier to just
say to use a release build type.
