gnu: gcc: Update cpu tuning architectures.

* gnu/packages/gcc.scm (%gcc-7.5-armhf-micro-architectures): Add missing
micro-architecture.
(%gcc-10-armhf-micro-architectures): Adjust accordingly.
(%gcc-11-aarch64-micro-architectures): Add missing micro-architecture.
(%gcc-12-aarch64-micro-architectures, %gcc-12-armhf-micro-architectures,
%gcc-12-x86_64-micro-architectures, %gcc-13-aarch64-micro-architectures,
%gcc-13-armhf-micro-architectures, %gcc-13-x86_64-micro-architectures):
New variables.
(gcc-12)[properties]: Use new compiler-cpu-architectures.
* guix/cpu.scm (cpu->gcc-architecture): Update entries for Intel, AMD,
x86_64 fallback and aarch64.
