[clang-format] [PR43372] - clang-format shows replacements in DOS files when no replacement is needed

Summary:
This is a patch to fix PR43372 (https://bugs.llvm.org/show_bug.cgi?id=43372) - clang-format can't format file with includes, ( which really keep providing replacements for already sorted headers.)

A similar issue was addressed by @krasimir in {D60199}, however, this seemingly only prevented the issue when the files being formatted did not contain windows line endings (\r\n)

It's possible this is related to https://twitter.com/StephanTLavavej/status/1176722938243895296 given who @STL_MSFT  works for!

As people often used the existence of replacements to determine if a file needs clang-formatting, this is probably pretty important for windows users

There may be a better way of comparing 2 strings and ignoring \r (which appear in both Results and Code), I couldn't choose between this idiom or the copy_if approach, but I'm happy to change it to whatever people consider more performant.
