  [mlir] Support slicing for operands in results in Python bindings

Slicing, that is element access with `[being:end:step]` structure, is
a common Python idiom for sequence-like containers. It is also necessary
to support custom accessor for operations with variadic operands and
results (an operation an return a slice of its operands that correspond
to the given variadic group).

Add generic utility to support slicing in Python bindings and use it
for operation operands and results.
