<summary>Changes</summary>

The new test added in https://github.com/llvm/llvm-project/pull/132783 was 
failing on Windows because it created a new error to say it did not support the 
feature, but then returned the existing, default constructed error. Which was a 
success value.

This also changes the GDBRemote error message to the same phrasing used in all 
the other places so we don't have to special case any platform.
