- modify the input hash debug dump mechanism to output an empty "debughash_<hash>" file instead of a txt file with the hash in contents, and always dump these files for the instance of the job that actually compiled
- the existing cvar will now just make it so these files are also dumped for jobs which hit in DDC or the job cache; we don't do this by default so there's only a single match for the debug hash for any given shader normally and it is inside the folder containing the full debug info, including those artifacts which are only output as a side effect of the compile step
- add the same hash as the first line in the stripped source code, so "debughash_<hash>" can be used as a search term in Everything to quickly find debug info associated with a shader (i.e. when looking at a capture in renderdoc or similar)

note: this is a resubmit with fixes for mac/linux issues (avoiding printfs and using string builders instead; since wchar_t and TCHAR are not the same size on these platforms using %ls does not work), and a further fix for problems encountered with source compression when using wide chars in preprocessing instead of ansi chars.
