Fix Symbol.ranges unpacking

The Symbol.ranges attribute in kconfiglib returns 4-tuples (low, high,
cond, loc), but menuconfig and guiconfig were using the old 3-tuple
unpacking pattern, causing ValueError when processing integer/hex symbols
with range properties.

Changes:
- Update all sym.ranges unpacking to handle 4-tuple format
- Use underscore (_) for unused location parameter to indicate intent
- Standardize on sym.orig_type instead of sym.type for consistency with
  kconfiglib internals and to avoid potential issues with type transformations
