[skip ci] Add nightly job for x64 Windows with ASan enabled

It seems reasonable to have an ASan job on Windows, especially to be
able to check Windows specific code.  Since the tests may take about
70 minutes, it doesn't make sense to add these for pushes, but for a
nightly job that should be okay.

Closes GH-17087.
