[Support] Beef up and expose the response file parsing in llvm::cl
The plan is to use it for clang and lld. Major behavior changes: - We can now parse UTF-16 files that have a byte order mark. - PR16209: Don't drop backslashes on the floor if they don't escape anything. The actual parsing loop was based on code from Clang's driver.cpp, although it's been rewritten to track its state with control flow rather than state variables.
