[release/6.0] Remove duplicate entries from dotnet --info

[github-actions]

Backport of #60376 to release/6.0

/cc @ericstj

Customer Impact

Customers see duplicate entries in dotnet --info for all SDKs and all frameworks when running in the default install on Windows. Regression introduced in RC2. This isn't blocking but it looks pretty bad.

Testing

Manually tested end-to-end to verify fix (shown below). Added automated regression test.

Risk

Very low. Leverages existing method in a new place.

Root cause

We are writing a trailing slash on InstallLocation and the host didn't remove this when considering paths (though it does for other paths). The result is that it considers C:\Program Files\dotnet and C:\Program Files\dotnet\ to be separate paths, causing duplicates. Fixing this to avoid the trailing slash in the installer requires a custom action. The reason it worked before was because the installer was using hard-coded strings to write these values. We changed that in ARM64 work to calculate these directories. MSI insists on directories ending in a trailing slash.

Result before:

Thanks!

approved over mail.

Test failure is An error occurred trying to start process '/root/runtime/artifacts/tests/Release/ahb/1gni15vk.qjx/SingleFileApiTests/bundle/SingleFileApiTests' with working directory '/root/runtime/artifacts/bin/AppHost.Bundle.Tests/Release/net6.0'. Text file busy

Probably just a coincidence that this is in a host test, right? Especially since we only change the windows PAL. Rerunning though to increase confidence that I didn't cause some butterfly effect.

[vitek-karas]

That failure is fixed in 7 (right @agocke?), and it's a completely random failure affecting all single-file tests, but basically nothing else.

[agocke]

Sorry for the delay -- yes this race should be fixed in main. I'll consider backporting.
