Use `zig cc` as another assembler

[peace-maker]

btw we moved to zig, both for cross-compiling (pwndbg/pwndbg#2935, pwndbg/pwndbg#3202) and cross-assembling (pwndbg/pwndbg#3207), so we now include zig as a python package with pwndbg and don't need to worry about what toolchain the user has installed

maybe a similar approach would be neat for pwntools

I'd keep the binutils integration but have the zig solution as a fallback or additional option. This will make assembling on Windows less painful.
