    adapter: list supported transports beside adapter name
    
    Modify the command 'adapter list' to output the list of transports
    supported by each adapter driver.
    Drop the line number, as there is no real interest on it.
    Format the output as a TCL dictionary indexed by the adapter name
    and containing the transports in a TCL list. E.g:
            dummy          { jtag }
            ftdi           { jtag swd }
    
    This format is easily handled by TCL scripts, e.g.:
            dict get [adapter list] ftdi
