Title:
  gdb crashes upon `run` on some arm64 machines

Status in gdb package in Ubuntu:
  Fix Released
Status in gdb source package in Lunar:
  Fix Released

Bug description:
  [ Impact ]

   * gdb 13.1 as shipped in lunar is affected by a bug where it crashes upon `run` 
     on some arm64 machines (confirmed on Apple M-series, both under hypervisor 
     and bare metal, everything else with PAC should also be affected).

   * It was fixed upstream in gdb 13.2: https://inbox.sourceware.org/gdb- 
     patches/20230316103904.1947447-1-luis.machado at arm.com/.

   * Debian bookworm's gdb_13.1-3 also includes the same patch as `aarch64-pauth- 
     registers.patch`.

  [ Test Plan ]

   * This diff is confirmed to fix gdb 13.1 in lunar on my arm64 laptop.

   * This could be tested by running any program under lunar's gdb 
     on any ARM64 PAC machine.

  [ Where problems could occur ]

   * Problems aren't particularly likely as the exact patch was included in the 
     last Debian stable.

   * In theory, a gdb rebuild could possibly cause breakage.
