The build should report suggested remappings from the ClangSharp output

[sotteson1]

I was working on a bug and realized I had forgotten that ClangSharp will tell you about typedefs that show you might want a remapping (e.g. tagMY_STRUCT to MY_STRUCT). I added a bunch of new mappings from this data.

I used this command to display them:

 get-childitem .\generation\WinSDK\obj\scratch\ -Recurse -Filter '*.txt' | select-string -Pattern "Recommended remapping: \'([^\']*)\'" | ForEach {$_.Matches} | select-object {$_.Groups[1].Value} -Unique

We can't just take all of these as remappings, because many of them are from typedefs that would make things worse. So, we would need a file to keep track of known ones we want to ignore. The build would then look for items using something like command above, but then filter out items using the known list.
