Remove dead legacy GL Texture class

texture.hpp / texture.cpp implemented an unfinished OpenGL texture loader
(loadFromFile was a TODO stub) that had no callers — the project's texture
loading is entirely handled by VkTexture (vk_texture.hpp/cpp) after the
Vulkan migration. Remove both files and their CMakeLists entries.
