Expand description

The supported unwind codes for the x64 Windows ABI.

See: https://docs.microsoft.com/en-us/cpp/build/exception-handling-x64 Only what is needed to describe the prologues generated by the Cranelift x86 ISA are represented here. Note: the Cranelift x86 ISA RU enum matches the Windows unwind GPR encoding values.
