[lldb][PDB] Update max matches test for type queries (#75813)

NestedClass will be found via Class::NestedClass and
ClassTypedef::NestedClass. So the first part of the test gets 2 results
as the default is to find all matching types.

In the next part, we ask for only the first match and expect to get only
1 of those two possible results.
