[Vulkan] Factories and general controller cleanup

- Added working texture factory ( some features are still missing )
- Started work on the shaders factory in order to instatiate custom pipeline
- Textures are created with the factory
- Added shader factory
- API::Shader is more like old Program rather than VkShaderModule
- Added support for binary and text shader source
- For now only SPIRV language is supported
- Only vertex and fragment shader stages supported

Known issue:
- Due to not being cached, shaders are being created again when mouse enters the window area
