SPL pretty printers for QT debugger

(use this issue to track various quirks to be aware of)

Clang change for arm M1 broke pretty print of C++ string, we patched in library personaltypes.py file

Qt tracker shows fix released April 2023, I tested on various config, seems to be good, removed our patch to avoid conflict

Fixes to be added Fall 2023 :

• Correct handling to expand nested types (key/value type for Map/HashMap/PriorityQueue is collection/pointer/struct)
• add pretty printers for GridLocation, GridLocationRange, Bit

Some things broken again on macOS Fall 2024. Need fixes for std::string and HashSet/Map

Pretty printers now working for all Stanford types as of Fall 2024.

Fall 2025, Qt 6.9: Linear collections (Vector/Stack/Queue/Grid) okay, but pairs (Set/Map) need help. The QT-supplied pretty printers for map/unordered_map also broken

[zelenski]

Last fall, Qt was not computing correct alignment for a struct, just used guess of 8. This worked for most of the cases that mattered to us.
Version 6.9 Qt now tries to compute alignment but iterates over get_fields_array() when it should instead bget_members_array(). This will ignore base class members which means classes like string and compressed_pair are utterly broken (thinks alignment is 1). I put in a patch into stanfordtypes.py to correctly calculate alignment and use that instead when dissecting pairs. This corrects pretty printers for Map/HashMap/Set/HashSet.
