Shannon Booth e2e7c4d574 Everywhere: Use to_number<T> instead of to_{int,uint,float,double}
In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:

```
Optional<I> opt;
if constexpr (IsSigned<I>)
    opt = view.to_int<I>();
else
    opt = view.to_uint<I>();
```

For us.

The main goal here however is to have a single generic number conversion
API between all of the String classes.

// FIXME: C.refs is the set funcidx(module with funcs=ϵ with start=ϵ),
// i.e., the set of function indices occurring in the module, except in its functions or start function.
// This is rather weird, it seems to ultimately be checking that `ref.func` uses a specific set of predetermined functions:
// The only place where this is accessed is in validate_instruction<ref_func>(), but we *populate* this from the ref.func instructions occurring outside regular functions,
// which limits it to only functions referenced from the elements section.
// so the only reason for this (as I see) is to ensure that ref.func only hands out references that occur within the elements and global sections
// _if_ that is indeed the case, then this should be much more specific about where the "valid" references are, and about the actual purpose of this field.
//
// For now, we simply assume that we need to scan the aforementioned section initializers for (ref.func f).
