Handle huge integers in OpenQASM 2 expression evaluator (#12140)

* Handle huge integers in OpenQASM 2 expression evaluator

This modifies the expression evaluator to directly parse the backing
string data of an integer token in a floating-point context, which lets
us handle numbers that would otherwise overflow a `usize`.  It's
possible for this to be totally valid, if, for example, the integer is a
multiple of some very large power of two that doesn't overflow a
double-precision float.

We already needed to immediately cast the integer to a float, so this is
just a more accurate way of doing the evaluation, and doesn't affect
when we use integers in other contexts.

* Clarify int/float split
