Automerge: [NFC][SemaHLSL] Remove check dependent on non-deterministic root element association (#148649)

- when there are duplicate (equivalent) `RangeInfo`s created we will
attempt to `llvm::sort` or `llvm::stable_sort` them, it does not appear
deterministic in which order they will be sorted (because they are
equivalent)

- when `DLLVM_ENABLE_EXSTENSIVE_CHECKS` is enabled, it appears to deal
with this tie-breaker sorting the list differently than when it is not
enabled, this causes one of the test cases to fail because the
diagnostic is produced, not in a different order, but with a different
root element associated with an identical `RangeInfo`

- functionally this makes no difference to the diagnostic being produced
and the removed test-case was added just as a nicety to demonstrate how
the diagnostics might look

- the test above the removed will correctly demonstrate that the
`SourceLocation` will be set to the correct column, and, the `-verify`
portion of this testcase will ensure that we still generate a diagnostic
for each duplicate

- therefore, it is safe to remove this portion of the test-case that can
have a non-deterministic association of root element

This resolves the build issues reported
[here](llvm/llvm-project#147115 (comment))
and
