* Factor out AppGLFW base class

The intention here is to get rid of scaffolding in the consumer
application class and allow to focus on the "important bits".

* Some cleanup

* dump unnecessary dependency

* link stuff where needed & use only what's needed

* remove deprecation warnings

* add gallery toggle

* make some includes private

* add presets

* remove dir locals, use presets instead

`projectile-configure-project' in conjunction with CMakePresets.json
will allow to configure the project.
`projectile-compile-project' does sth similar for the compile command.

This is equivalent to something like
~cmake --preset clang-debug && cmake --build build --preset clang-debug~

* use presets in pipeline
