Change object representation from 1 big union to individual structs. A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).

typedef enum {
Implement __bool__ and __len__ via unary_op virtual method for all types. __bool__() and __len__() are just the same as __neg__() or __invert__(), and require efficient dispatching implementation (not requiring search/lookup). type->unary_op() is just the right choice for this short of adding standalone virtual method(s) to already big mp_obj_type_t structure.

py: Simplify fastn in VM; reduce size of unique code struct. We still have FAST_[0,1,2] byte codes, but they now just access the fastn array (before they had special local variables). It's now simpler, a bit faster, and uses a bit less stack space (on STM at least, which is most important). The only reason now to keep FAST_[0,1,2] byte codes is for compressed byte code size.
