Add indexing and bitshift expressions (#12310)

This adds the concepts of `Index` and the binary operations `SHIFT_LEFT`
and `SHIFT_RIGHT` to the `Expr` system, and threads them through all the
`ExprVisitor` nodes defined in Qiskit, including OQ3 and QPY
serialisation/deserialisation.  (The not-new OQ3 parser is managed
separately and doesn't have support for _any_ `Expr` nodes at the
moment).

Along with `Store`, this should close the gap between what Qiskit was
able to represent with dynamic circuits, and what was supported by
hardware with direct OpenQASM 3 submission, although since this remains
Qiskit's fairly low-level representation, it still was potentially more
ergonomic to use OpenQASM 3 strings.  This remains a general point for
improvement in the Qiskit API, however.
