Dominique Belhachemi 36f655f44c GH-51476: [C++][Parquet] Vectorise FindMinMax explicitly (#51478 )

### Rationale for this change

FindMinMaxAvx2 in parquet/level_comparison_avx2.cc was not vectorised. 

### What changes are included in this PR?

A single xsimd kernel `FindMinMaxSimd<Arch>` in `level_comparison_simd_kernel_internal.h`,
plus support for multiple architectures.

### Are these changes tested?

Yes, with a nice speedup.
| dispatch level | time |
|---|---|
| NONE | 513 ns |
| SSE4_2 | 54.9 ns (9.3x) |
| AVX2 | 28.7 ns (17.9x) |

### Are there any user-facing changes?
