feat(gx): add incomplete 'CGxDeviceGLSDL' (#2)
* chore(build): add vendored SDL 3.0.0 library * chore(build): add vendored glew-cmake-2.2.0 library * feat(console): in the presence of -opengl launch flag, change GxApi to OpenGl * feat(gx): add uncompleted CGxDeviceGLSDL targeting Windows and Linux * chore(build): change SDL3 linkage from shared (bad) to to static (good)
