Clean up LLFile and LLFilesystem operations to reduce temporaries allocations and utf8->utf16 conversions

Fix LLFile::tmpdir failing when temp directory is located in a unicode path on windows
Add Tracy profiler tagging to LLFile that's disabled by default
Replace LLFile::utf8StringToWstring with our fsyspath std::filesystem::path adapter
Introduce std::filesystem::path to llifstream/llofstream wrappers
Add move operators to fsyspath to match copy operator
Restore LLUniqueFile RAII class for direct c file io wrapping and reducing merge conflicts with downstream code that may depend upon it
