commit 9d5f833fbd47a5a0631fa1f6f1734f277fdde342

    tcl/target: fix rp2040-core0.cfg work area backup.
    
    The work area should be backed up.
    The flash probe runs an algorithm on the target CPU.
    The flash is probed during gdb connect if gdb_memory_map is enabled
    (is enabled by default).
    Without backup the target memory gets corrupted on gdb connect.
