According to the post https://developer.apple.com/forums/thread/676684, the executable whose size is bigger than 2G may fail to start. The size of the executable `doris_be_test` generated by run-be-ut.sh is 2.1G (> 2G) now and we can't run it on macOS (arm64). We can separate the debug info from the executable `doris_be_test` to reduce the size. After that, we can run `doris_be_test` successfully.
