Make our local .NET the default .NET (in the root's global.json), and then if
a directory wants to use the system .NET, then that directory would have to
opt-in (using its own global.json).
This way we don't have to copy global.json/NuGet.config files around to run
tests with the correct .NET setup.
* Don't execute .NET tests in the 'legacy' targets (it's wasteful because
we're already executing those .NET tests elsewhere).
* Fix reporting failures in the legacy tests.
I recently deleted the generated makefile support for building and running our
test suites. It turned out that it was used for building the packaged
Xamarin.Mac tests, so it wasn't as unused as I thought.
So fix the building and packaging of Xamarin.Mac tests to not use the
(non-existent) makefile targets, but instead replicate it with manual make
code.
Also take the opportunity to add packaging and execution of the .NET versions
of these test suites we execute on other macOS versions (both for macOS and
the Mac Catalyst).
* [devops] Use stricter matching when finding the Xamarin.Mac pkg link.
Otherwise the branch name in any package could end up matching the pattern we
were looking for:
XM_PACKAGE=https://bosstoragemirror.blob.core.windows.net/wrench/tests-package-xamarin-mac-tests/15759261d425ae08494b0a26862a0b1356c5f8ec/5268864/package/Microsoft.iOS.Bundle.15.0.101-ci.tests-package-xamarin-mac-tests.68.pkg
is just clearly wrong.
