[wasm] Fix Vector128 SIMD fmin and fmax

[radekdoulik]

Fix #92885

Min and max now use NaN propagating SIMD instructions, f32x4.min, f64x2.min, f32x4.max and f64x2.max.

Example emitted code:

...
f32x4.min    [SIMD]
v128.store    [SIMD]

for

return Vector128.Min(/* Vector128<float> */ v1, v2);

I think we can try to unify all the platforms to use llvm.[maximum|minimum].[v4f32|v2f64] intrinsics for v128. Lets keep it simple for this PR so that it is easier to backport to NET8.
