perf(deps): switch to upstream nanors runtime dispatching

[cgutman]

Description

Nanors has implemented their own runtime dispatching so our rswrapper hack is no longer required to use more advanced ISA extensions. In addition to runtime dispatching, they have also implemented a number of new handwritten assembly routines to improve performance on x64, ARM64, and RISC-V (GFNI, NEON, and RVV).

@ReenigneArcher Any clue what's up with the Arch and Flatpak builds?

@ReenigneArcher Any clue what's up with the Arch and Flatpak builds?

Yes, it randomly fails to checkout the ref. I think I have to revert it to checking out the fork branch directly.

For now, it can usually be resolved by forcing a push (though the hash must change).
