  [lldb] Expose a const iterator for SymbolContextList

There are many situations where we'll iterate over a SymbolContextList
with the pattern:
```
SymbolContextList sc_list;
// Fill in sc_list here
for (auto i = 0; i < sc_list.GetSize(); i++) {
  SymbolContext sc;
  sc_list.GetSymbolAtContext(i, sc);

  // Do work with sc
}
```
Adding an iterator to iterate over the instances directly means we don't
have to do bounds checking or create a copy of every element of the
SymbolContextList.
