CI: Reduce build times by reusing generated headers (#2254)

* reuse generated headers inbetween runs

* properly access env var

* fix windows compiler arg

* reintroduce ubuntu24 ci compilers

* fixed CXX_MODULES flag logic

* echoing build parameters, removing use of Ninja from windows CI

* fixed echo and temporarily disabled all but windows CI

* reenabled all ci

* compile glm, glfw and glslang once, fixed SPIRV include path

* remove usage of Ninja from windows ci (again)

* fixed glfw name to glfw3

* removed.. debug things

* remove dep install step from windows, enforce correct linking in utils

* compiling generators in debug mode without running them
