Fix: [CMake] our allegro drivers use v4, so skip v5 if found (#8653)

On some distros allegro v5 is called allegro-5, but on some others
it is not. So this should fix for all distros that allegro v5 is
not being picked up, and only v4 is.

Add: introduce CMake for project management

CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.

Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.

This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.

Addtiionally, this heavily improves our detection of libraries, etc.
