[MC] [Win64EH] Avoid producing malformed xdata records
If there's no unwinding opcodes, omit writing the xdata/pdata records.
Previously, this generated truncated xdata records, and llvm-readobj
would error out when trying to print them.
If writing of an xdata record is forced via the .seh_handlerdata
directive, skip it if there's no info to make a sensible unwind
info structure out of, and clearly error out if such info appeared
later in the process.
