toolchain/toolchain-external/toolchain-external-arm-aarch64: bump to version 12.2-rel1

Updated to gcc 12.2, gdb 12, binutils 2.39, glibc 2.36.

Upstream changed version scheme previously based on the release
date (2021.07) to a version scheme based on gcc version (12.2.rel1).

The runtime issue (Illegal instruction on some x86 host) [1] seems to
be fixed since it can't be reproduced anymore on the same host.

The x86_64 host variant prebuilt toolchain is built on RHEL7
(glibc 2.17) and is likely also be useable on OS versions like
RHEL8, Ubuntu 18.04 or later.

The AArch64 host variant prebuilt toolchain is built on Ubuntu 18.04
(glibc 2.27) is likely also be useable on OS versions like RHEL8,
Ubuntu 18.04 or later.

Use the sha256 hash that is now provided by upsteam.

Tested with qemu_aarch64_virt_defconfig.
