Review test changes from #43015

[Youssef1313]

Part of the changes from #43015 are being reverted as part of #45295 as they were not correct. Some other tests are ignored but that's tracked by #42850

There are more changes that may need to be reviewed by the SDK team:

• It_fails_to_build_if_targeting_a_higher_framework_than_is_supported: this changed the test argument from netcoreapp9.1 to netcoreapp10.1. I don't see a reason why the test would fail with netcoreapp9.1 so to me, the test should be tested both with netcoreapp9.1 and netcoreapp10.1. Add netcoreapp9.1 tfm to It_fails_to_build_if_targeting_a_higher_framework_than_is_supported test #45409
• Bunch of test assets were updated from <TargetFramework>$(CurrentTargetFramework)</TargetFramework> to net9.0 which is suspicious to me. Update the hardcoded tfm to the current #45720
• WorkloadTests used to use ToolsetInfo.CurrentTargetFramework but are now using hardcoded net9.0. Investigate failures in WorkloadTests when using net10.0 workload manifests #45516
• WebProjectsTests.CanShowHelp_Mvc.verified.txt is showing -f, --framework <net10.0|net6.0|net7.0|net8.0> The target framework for the project. which is strange that net9.0 is missing from there while old EOL TFMs are there. Add support for .NET 9.0 web project templates #45423
• Changes in CommonTemplatesTests looks suspicious to me. Create project templates target to 10.0 #44349
• It_defaults_preview_AnalysisLevel_to_the_next_tfm is fixed and is ignored in Fix warning level calculation for .NET 10 #45295 with link to this issue.

NOTE: It's possible that some of the test changes are not wrong per-se and are temporary until other parts of the ecosystem release their stuff. In that case it's still good to have a tracking issue to revert when the time comes

@v-wuzhai do you mind taking a look at this and see if there are any here that you can sort out and resolve?

These changes are primarily to support the transition from .NET 9.0 to .NET 10.0. We have updated the test frameworks and related code to ensure compatibility and validate new features in the latest version. However, these changes might be temporary, and we will gradually revert them as other parts of the ecosystem release their updates.

Given that all related issues are being tracked and addressed separately, this PR will be closed.
