Enable arcade support (#113)

* Copy eng\common from Arcade repo.

* Enable Spark to build using dotnet/arcade

* Update coverlet version to work around bug in older version.

* Fix up test directory lookup for new artifacts location.

* Don't use dummy versions for local dev builds.

* Fix up official build for new output artifacts location

* Rearrange official build

- Set official build id parameter
- Build nuget package on Build leg
- Publish the worker using MSBuild instead of cmd

* Ensure only our .nupkg gets signed and copied, and the .nupkg is placed directly in the Packages folder.

Clean up official build definition.

+
+That's a very nice catch!
+
+We do not support building tracepoint probe provider with
+g++ yet, as stated in lttng-ust(3):
+
+"- Note for C++ support: although an application instrumented with
+   tracepoints can be compiled with g++, tracepoint probes should be
+   compiled with gcc (only tested with gcc so far)."
+
+However, if it works fine with this fix, then I'm tempted to take it,
+especially because removing the empty union does not appear to affect
+the layout of struct lttng_event as seen from liblttng-ust, which must
+be compiled with a C compiler,  and from probe providers compiled with
+a C compiler. So all we are changing is the layout of a probe provider
+compiled with a C++ compiler, which is anyway buggy at the moment,
+because it is not compatible with the layout expected by liblttng-ust
+compiled with a C compiler.
