GH-47446: [C++] Update Meson configuration with compute swizzle change (#47448)

### Rationale for this change

The Meson configuration for compute was broken after the vector swizzle change was introduced; this gets the Meson configuration at parity with CMake again

### What changes are included in this PR?

Move `vector_swizzle.cc` to `libarrow` from `libarrow_compute`.

See also: #47378

### Are these changes tested?

Yes 
### Are there any user-facing changes?

No
