shared/readline: Use MP_REGISTER_ROOT_POINTER().

Browse Source 
This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root
pointer array used by shared/readline.c and removes the registration from
all mpconfigport.h files.

This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

#define MP_STATE_PORT MP_STATE_VM
#define MICROPY_PORT_ROOT_POINTERS \
const char *readline_hist[8];
This configuration file contains machine-specific configurations including aspects like if different
MicroPython features should be enabled e.g. ``#define MICROPY_ENABLE_GC (1)``. Making this Setting
``(0)`` disables the feature.
