A new ErrorCode enumeration is present in PluginInterface which can be used when returning an llvm::Error from offload and PluginInterface functions. This enum must be kept up to sync with liboffload's ol_errc_t enum, so both are automatically generated from liboffload's enum definition. Some error codes have also been shuffled around to allow for future work. Note that this patch only adds the machinery; actual error codes will be added in a future patch. ~~Depends on #137339 , please ignore first commit of this MR.~~ This has been merged.
