build: Revise the build system

This revises the build system to have configuration per system
component. System settings can now be set using cmake.

The standard compliance defines were removed from configuration header
and are set in the sources where needed. Also some small code
refactors, such as moving the data for shims out of the ipcp structure
to the respective shims were performed.
