Add an azure-pipelines.yml

v1:
Add an azure-pipelines.yml
Don't check source line endings if autocrlf is on
Handle origin-only refs in skip_ci
Add .py to PATHEXT for the benefit of test_find_program()
Publish logs as build artifacts and publish test results

v2:
Use .gitattributes to override autocrlf
Move tmpdir, so it's not a subdir of source directory, otherwise it gets
included in line-ending checks.
Use serial build numbers, rather than date.dailybuildnumber
Workaround for #3239 is no longer needed now a fix has been commited
Tweak test results and artefact naming
Wait for MS-MPI installers to complete
Publish test results even if tests had an error
