  Make SBMemoryRegionInfoList iterable with Python SWIG (#117358)

This PR fixes a simple SWIG issue with SBMemoryRegionInfoList not being
iterable out-of-the-box. This is mostly because of limitations to the
`lldb_iter` function, which doesn't allow for specifying arguments to
the size / iter functions passed.

Before:
```
(lldb) script
Python Interactive Interpreter. To exit, type 'quit()', 'exit()' or Ctrl-D.
>>> for region in lldb.process.GetMemoryRegions():
...   print(region)
...
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/opt/llvm/stable/Toolchains/llvm-sand.xctoolchain/usr/lib/python3.10/site-packages/lldb/__init__.py", line 114, in lldb_iter
    yield elem(i)
TypeError: SBMemoryRegionInfoList.GetMemoryRegionAtIndex() missing 1 required positional argument: 'region_info'
```

After:
```
(lldb) script
Python Interactive Interpreter. To exit, type 'quit()', 'exit()' or Ctrl-D.
>>> for region in lldb.process.GetMemoryRegions():
...   print(region)
