Add basic MSI tests to CI

[pjanotti]

Resolve #576 by adding smoke tests to the MSI package created for Windows. This follow the pattern as the package-tests written for deb and rpm packages. The tests are limited to amd64 since this is the most common target for Windows and the MSI code itself doesn't differ per CPU architecture.

The tests themselves are written in go to facilitate future additions to the tests, e.g.: upgrade scenarios. I opted to add dedicated go.mod and go.sum to not mix the test dependencies with the ones on the repository root.

I can see the test running and passing on this PR https://github.com/open-telemetry/opentelemetry-collector-releases/actions/runs/12261110160/job/34207631963?pr=753 👍

I'd love to see a Makefile target, so that I can easily run these tests on my local machine or in any other environment. This would help in reproducibility of the test.

Also (or maybe instead of the Makefile target) documentation describing the prerequisites, like building the MSI package first.

@andrzej-stencel the challenge here is that to build the MSI locally I think one needs to have a goreleaser key to the pro version. I think a Powershell script that sets up the environment variables required by the test could be a good follow-up. So instead of setting up those on the CI job we use the script to do that instead and same script can be used locally with any MSI that the user wants.
