Python: gpu module: add new submodules and types
This commit extends the gpu python API with:
```
gpu.types.Buffer #"__init__", "to_list"
gpu.types.GPUTexture #"__init__", "clear", "read", "format"
gpu.types.GPUFrameBuffer #"__init__", "bind", "clear", "is_bound", "viewport", ("__enter__", "__exit__" with "GPUFrameBufferStackContext")
gpu.types.GPUUniformBuf #"__init__", "update"
gpu.state #"blend_set", "blend_get", "depth_test_set", "depth_test_get", "depth_mask_set", "depth_mask_get", "viewport_set", "viewport_get", "line_width_set", "line_width_get", "point_size_set", "color_mask_set", "face_culling_set", "front_facing_set", "program_point_size_set"
```
Add these methods to existing objects:
```
gpu.types.GPUShader #"uniform_sample", "uniform_buffer"
```
