Python: Add platform feature support methods to `gpu.capabilities` module. 

Depending on the actual platform, Blender will disable features that are
known to have a faulty implementation. Add-on developers or users don't
have the ability to check what is actually enabled.

This patch will add the ability to check for

* Compute shader support `gpu.capabilities.compute_shader_support_get()`.
* SSBO support `gpu.capabilities.shader_storage_buffer_objects_support_get()`.
* Image load/store `gpu.capabilities.shader_image_load_store_support_get()`.
