simde_mm_movemask_ps native implementation errantly depends on MMX

[tycho]

https://github.com/simd-everywhere/simde/blob/647dc121216f12ddedea82ce5da5662f158c856b/simde/x86/sse.h#L3171-L3176

This is an SSE instruction and has nothing to do with MMX, the && defined(SIMDE_X86_MMX_NATIVE) should be removed here. I can see how this likely happened though, since several of the surrounding functions do carry dependencies on MMX. I suspect this was a copy/paste error.
