py/modbuiltins: Implement abs() by dispatching to MP_UNARY_OP_ABS.
...
This allows user classes to implement __abs__ special method, and saves
code size (104 bytes for x86_64), even though during refactor, an issue
was fixed and few optimizations were made:
* abs() of minimum (negative) small int value is calculated properly.
* objint_longlong and objint_mpz avoid allocating new object is the
argument is already non-negative.

all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriate
...
The unary-op/binary-op enums are already defined, and there are no
arithmetic tricks used with these types, so it makes sense to use the
correct enum type for arguments that take these values. It also reduces
code size quite a bit for nan-boxing builds.

py/objint: In int.from_bytes, only create big-int if really needed.
...
This patch ensures that int.from_bytes only creates a big-int if necessary,
by checking the value for a small-int overflow as it's being parsed.

This reduces code duplication and allows to make mp_classify_fp_as_int
static, which reduces code size.

py/objint: Allow to print long-long ints without using the heap.
...
Some stack is allocated to format ints, and when the int implementation uses
long-long there should be additional stack allocated compared with the other
cases. This patch uses the existing "fmt_int_t" type to determine the
amount of stack to allocate.

py/objint: from_bytes(): Implement "byteorder" param and arbitrary precision.
...
If result guaranteedly fits in a small int, it is handled in objint.c.
Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should
be implemented by individual objint_*.c, similar to
mp_obj_int_to_bytes_impl().

One never needs to format integers with a base larger than 16 (but code
can be easily extended beyond this value if needed in the future).

py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.

And also simplify it to remove the check for small int. This can be done
because this function is only ever called if the argument is not a small
int.

py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.
...
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure. So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that). This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.
