Fixes issue #19121 "dimension numbers placed lower than normal".
Problem:
QGCustomText has a new method `alignmentRect` which can optionally return a
`tightBoundingRect` instead of the regular `boundingRect`. The
`alignmentRect` is used for laying out the `QGIDatumLabel`, however
QGraphicsItemGroup's `childrenBoundingRect` use the childrens'
`boundingRect` and knows nothing of `alignmentRect`. The result is an
improperly sized label and frame and miss alignment. Additionally
`childrenBoundingRect` calculations includes hidden views, so even though
the `m_tolTextOver` and `m_tolTextUnder` are hidden they still affect
the bounding rect size.
Solution:
1. Implement new method `QGIDatumLabel::tightBoundingRect` this
calculates the bounding rect using the subview's
`aligmentRect` if there is text in the custom text.
2. Use `tightBoundingRect` in place of `boundingRect` to for the drawing of
arrows and the exact dim frames.
3. This PR acknowledges that there are some edge case fonts that while not
clipped may not interface perfectly with arrows and the exact dimension
frame.
4. Fix vertical alignment of `m_tolTextOver` / `m_tolTextUnder`
5. Incorporate PR Review comments
- additional geometry types

- add switch for matcher/LTNP on/off
- left justify tolerances
- use format spec for tolerance == zero
- prevent uncommanded tolerance format changes
- use 'w' format for HoleShaftFit
- allow zero tolerance values for HoleShaftFit
* [TD] remove unused headers
- also some sorting
- also improve readability by not using an abbreviation (we consistently don't abbreviate class names)
- separate validation, geometry and reference handling into
individual files
- improve 3d reference geometry handling
