GH-46386: [C++] Ensure using our CMake packages not Find*.cmake (#46387)

### Rationale for this change

If a downstream package has `FindArrow.cmake`, it may be used not our `ArrowConfig.cmake`.

### What changes are included in this PR?

Use `find_dependency(Arrow CONFIG)` instead of `find_dependency(Arrow)`.

### Are these changes tested?

Yes.

### Are there any user-facing changes?

Yes.
* GitHub Issue: #46386
