WillAyd opened a new issue, #46310: URL: https://github.com/apache/arrow/issues/46310
### Describe the enhancement requested The meson configuration issues some warnings from the -Wself-move option. These should be pretty easy to clean up, and I think would be good to add to the main CMake configuration: ``` ../src/arrow/util/small_vector_test.cc: In instantiation of ‘void arrow::internal::TestSmallStaticVector<Param>::CheckMove(bool) [with long unsigned int N = 5;
