    gdb/testsuite/rocm: Add the hip_devices_support_debug_multi_process proc
    
    It is not possible to debug multiple processes simultaneously on all
    generations of AMDGPU devices.  As some tests will need to debug
    multiple inferiors using AMDGPU devices, we need to ensure that all
    devices available have the required capability.  Failing to do so would
    result in GDB not being able to debug all inferiors properly.
    
    Add the hip_devices_support_debug_multi_process helper function used to
    ensure that all devices available can debug multiple processes.
