Use the correct canonical opcode name in the packed unwind table

[mstorsjo]

This was a leftover from the original tentative name before the real one was known.

Sorry for missing this...

Since the name is arbitrary, @pmsjt (whose fingerprints are on the Windows ARM64 unwind code) convinced me to shorten it to pac_sign_lr instead. I couldn't find any evidence the longer name is exposed anywhere except in a tool internal to Microsoft.

Ok, great, thanks! Yeah a shorter name would be convenient.

Although, I had just landed a change in LLVM making this name used in an external assembly directive name, in llvm/llvm-project@c43bff6. But since it literally landed a couple hours ago (and we're months away from a release), it's shouldn't be a problem to switch it over there to a less unwieldy name (and that's certainly appreciated).

Looks good to me. Thanks.
