    [fix](build) add -dead_strip on macOS to fix dyld cache crash for large BE binary (#61742)
    
    On macOS arm64, the doris_be binary (~2.2GB) has a virtual address space
    of ~6.7GB (4GB __PAGEZERO + 2.7GB segments), which overlaps with the
    dyld shared cache region. This causes "dyld cache not loaded: syscall to
    map cache into shared region failed", making all system libraries
    (libresolv, libiconv, CoreFoundation, etc.) fail to load and the BE
    process crash on startup.
    
    Adding -Wl,-dead_strip removes unreachable code and data, reducing the
    binary to ~1.7GB and the virtual address space to ~6.1GB, which avoids
    the dyld shared cache conflict.
