all: Simplify mp_int_t/mp_uint_t definition.

Assuming proper C99 language support, we can select "the int type as big as
a pointer" (most of the time) or "the 64-bit int type" (nanboxing with
REPR_D), and then define everything else automatically.

This simplifies port configuration files.  And the types can still be
overridden if needed.
