Norman Feske c629c54153 Make util/geometry.h C++20 friendly
- Move header to base/include to make it applicable for base types
  like 'Affinity' down the road.
- Represent 'Rect' as typle of point and area, which is the most
  common form of initialization, creates in valid 'Rect' by default.
- Turn Point, Area, and Rect into compound types, making x, y, w, h, at,
  area accessible without a method call
- 'Rect::Compound' function for constructing a 'Rect' from two points,
  replacing a former constructor
- Use result type 'Rect::Cut_remainder' instead of out parameters.

This directory is a source-code repository containing Genode-specific services
and applications. In contrast to the components hosted in the 'os' repository,
programs contained in 'gems' are able to leverage the functionalities provided
by higher-level repositories such as 'libports'. To use the 'gems' repository,
make sure to also add those repositories to your build configuraion.
