Switch BundleExtractToSpecificPath and BundleAndRun to using built test assets

[elinor-fung]

• Make BundleExtractToSpecificPath and BundleAndRun tests use built test asset project (HelloWorld)
  • The BundleExtractToSpecificPath tests explicitly include mockcoreclr so that it will have native binaries to bundle
• Remove redundant BundleAndRun.TestWith*Paths* tests
  • These were running a self-contained (not bundled) application by invoking it using relative / absolute paths, which does not seem particularly useful. There was no difference in how they bundled the application or ran the bundled application.
• Move codesign check to BundlerConsistencyTests - trying to separate tests targeting the Bundler API from tests targeting single-file activation

Fixes #91039

Looks good. Just curious: Do we understand how it fixes the "No space left on the device" failure?

I believe it was simply because we were copying so much around - a full self-contained application copied for every test case and then each test case would generate a bundle. While we were cleaning up, it was only after all the test cases were run (explicitly cleaning up the copies after each test case would probably also have fixed it).

This change (and the others switching to use the pre-built assets / SingleFileTestApp) just gets rid of all those copies of the entire runtime, since it grabs the runtime files from the shared framework location instead of building/copying around a self-contained application to get the runtime files.
