Summary of changes

Runs the CallTargetNativeTests on Windows

Reason for change

We weren't running these on Windows, and we should be

Implementation details

Add the RunOnWindows trait. Longer term I want to reverse the role of this trait, i.e. we run on windows by default and you add RunOnWindows=False to disable that.

Test coverage

More now

Other details

I thought we had a bug related to ref structs here, but it appears to be a Schrödinger's bug Oops, no, there it is!

@tonyredondo found the source of the issue - the /32BITREQ+ modification was failing because CallTargetNativeTest.exe is strong named, so we had to add the /force flag. And it has to be strong named because it references Datadog.Trace directly

Execution-Time Benchmarks Report ⏱️

Execution-time results for samples comparing the following branches/commits:

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

  • Welch test with statistical test for significance of 5%
  • Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

## Summary of changes

Runs the `CallTargetNativeTests` on Windows

## Reason for change

## Implementation details

## Test coverage

## Other details

~~I thought we had a bug related to ref structs here, but it appears to
