Currently, clang-offload-bundler has -inputs and -outputs options that accept
values with comma as the delimiter. This causes issues with file paths
containing commas, which are valid file paths on Linux.
This add two new options -input and -output, which accept one single file,
and allow multiple instances. This allows arbitrary file paths. The old
-inputs and -outputs options will be kept for backward compatibility, but
are not allowed to be used with -input and -output options for simplicity.
In the future, -inputs and -outputs options will be phasing out.

This patch refactors the HIP tool chain for new HIP tool chain, HIPSPV
tool chain, which is added in the follow up patch part 2.
Rename HIPToolChain to HIPAMDToolChain and Renames HIP.* files to HIPAMD.*.
Introduce HIPUtility.* file where common HIP utilities, shared among HIP
tool chain implementations, are placed in.
Move constructHIPFatbinCommand() and
constructGenerateObjFileFromHIPFatBinary() to HIPUtility. HIPSPV tool
chain is going to use them.
Tweak bundle target ID in constructHIPFatbinCommand(): extra dashes are
dropped if the Target ID is empty and 'hip' offload kind is made default
for non-AMD targets.
