meson: fix tests under Windows (#192)

* fix Windows tests

Need to use find_program to see if we can run this.

* github: add basic MSVC CI

* Fix Windows tests from git-archive tarball

diff fails when run from a tarball: the unittest programs produce CRLF
line endings and baseline_*.txt in the tarball uses LF.  Reproduce this
in CI by preventing Git from converting the text files to CRLF, then
ensure the unittest programs produce Unix line endings.
