Cleanup: Remove interface region files to C++

Moves all `interface_region*` files to C++ except for the tooptip region
which is slightly more complicated. Also move a few other files as well.
This helps to simplify and speed up code, especially through the use
of better C++ data structures. This change builds on all platforms on
the buildbot.

- * Pie menus can't contain more than 8 items (yet).
- * When using #uiItemsFullEnumO, a "More" button is created that calls
- * a new pie menu if the enum has too many items. We call this a new "level".
- * Indirect recursion is used, so that a theoretically unlimited number of items is supported.
- *
- * This is a implementation specifically for operator enums,
- * needed since the object mode pie now has more than 8 items.
- * Ideally we'd have some way of handling this for all kinds of pie items, but that's tricky.
