Add basicpy.numeric_constant op. 

* Going through TODOs on the PyTorch side, this is a big cause of them (not being able to have constants for signed/unsigned).
* Added complex while in here since we're at the phase where it is better to just have things complete than partially done.

let summary = "A constant from the Python3 numeric type hierarchy";
let description = [{
Basicpy re-uses core MLIR types to represent the Python3 numeric type
hierarchy with the following mappings:
* Python3 `int` : In python, this type is signed, arbitrary precision but
in typical realizations, it maps to an MLIR `IntegerType` of a fixed
bit-width (typically si64 if no further information is known). In the
future, there may be a real `Basicpy::IntType` that retains the true
arbitrary precision nature, but this is deemed an enhancement that
does not obviate the need to infer physical, sized types for many
real-world cases. As such, the Basicpy numeric type hierarchy will
always include physical `IntegerType`, if only to enable progressive
lowering and interop with cases where the precise type is known.
* Python3 `float` : This is allowed to map to any legal floating point
type on the physical machine and is usually represented as a double (f64).
In MLIR, any `FloatType` is allowed, which facilitates progressive
lowering and interop with cases where a more precise type is known.
* Python3 `complex` : Maps to an MLIR `ComplexType` with a `FloatType`
elementType (note: in Python, complex numbers are always defined with
floating point components).
* `bool` : See `bool_constant` for a constant (i1) -> !basicpy.BoolType
constant. This constant op is not used for representing such bool
values, even though from the Python perspective, bool is part of the
numeric hierarchy (the distinction is really only necessary during
promotion).
### Integer Signedness
All `int` values in Python are signed. However, there exist special cases
where libraries (i.e. struct packing and numpy arrays) interoperate with
unsigned values. As such, when mapping to MLIR, Python integer types
are represented as either signed or unsigned `IntegerType` types and can
be lowered to signless integers as appropriate (typically during realization
of arithmetic expressions where the choice is meaningful). Since it is not
known at the outset when in lowering this information is safe to discard
this `numeric_constant` op accepts any signedness.
