apacheGH-42109: [C++][CMake] Add preset for Valgrind (apache#42110)

### Rationale for this change

If we want to use Valgrind for our tests, we need to specify at least the following CMake options:

* `ARROW_RUNTIME_SIMD_LEVEL=AVX2`
* `ARROW_TEST_MEMCHECK=ON`

If we have a CMake preset for Valgrind, we don't need to remember them.

### What changes are included in this PR?

Add `features-valgrind` and `ninja-debug-valgrind` preset. `features-valgrind` is a hidden preset.

### Are these changes tested?

Yes. I used this to reproduce apache#42107 on local.

### Are there any user-facing changes?

No.
