[wpiutil] Replace llvm filesystem with C++17 filesystem (#3401)

Browse Source 
Use ghc::filesystem as fill on older GCC (e.g. RoboRIO).
This can be removed once all GCC platforms have upgraded to 8.1 or later.

File open functionality has been retained from LLVM but moved to "fs" namespace
and tweaked for improved consistency with std::filesystem (e.g. error_code is
passed by reference instead of returned).

Also update WPILibC's Filesystem functions to return std::string.
