target_request: replace command_print() with command_output_text()

To prepare for handling TCL return values consistently, all calls
to command_print/command_print_sameline should be ready to switch
to CMD as first parameter.

When dumping traces or semihosting text, the command that enabled
it is already completed, so CMD is not a valid value.
Plus, we want the dump to be printed in the command context where
the enable command was executed.

Replace command_print() with command_output_text().
