Add resource for failing to copy via hardlink

[Forgind]

Fixes https://github.com/dotnet/msbuild/pull/8238/files#r1125001007

Context

#8238 added a reference to "Copy.LinkLibraryFailedPrefix" but didn't actually add that to our .resx. This adds it.

Changes Made

Added a resource

Testing

Notes

[radical]

Can we add a test too - for a hardlink creation failing?

[rainersigwald]

Also validate that it contains Copy.RetryingAsFileCopy?

[rainersigwald]

Why not AssertLogContainsMessageFromResource as other places in this file?

[rainersigwald]

This doesn't make sense to me. Isn't it unix-only because we have an OS-specific p/invoke?

[Forgind]

We have matching p/invokes per OS, so one could suppose we could easily craft the appropriate error message a la:
if (NativeMethodsShared.IsWindows)
{
errorMessage = ...
}
else
{
errorMessage = ...
}

But that doesn't work because the windows version isn't from MSBuild and isn't preserved in any particularly relevant form. We can't craft an appropriate error from what's in the test, and I don't think it's worth it to try to plumb the error message back out to some output variable.

[rainersigwald]

Can you put this in CopyHardLink_Tests instead of the base class so it isn't run multiple times?

[JaynieBai]

@Forgind Sorry for awkward error. The new added test failed since there are not hard link creating failures in the same parent directory. we need a good way to inject failures for hardlink or symlink creation.

[Forgind]

Try making a 000 directory

That doesn't work. @Forgind I'm thinking if we could merge the product code fixes and skip the test cases at first. When we have the way to fail the hyperlink, we can enable the test case.

I agreed with @rainersigwald that since it's difficult to concoct a unit test that fails to create a hardlink on linux, I'd just test it manually and delete the unit test. My results from manual testing show:
Could not use a link to copy "/home/forgind/dotnet-install.sh" to "/mnt/c/Users/forgind/Desktop/di.sh". Copying the file instead. The link() library call failed with the following error code: 18. (TaskId:37)
