  [AArch64][PAC] Rework the expansion of AUT/AUTPAC pseudos

Refactor `AArch64AsmPrinter::emitPtrauthAuthResign` to improve
readability and fix the conditions when `emitPtrauthDiscriminator` is
allowed to clobber AddrDisc.

* do not clobber `AUTAddrDisc` when computing `AUTDiscReg` on resigning
  if `AUTAddrDisc == PACAddrDisc`, as it would prevent passing raw,
  64-bit value as the new discriminator
* move the code computing `ShouldCheck` and `ShouldTrap` conditions to a
  separate function
