360: Implement TEXTURE_BINDING_ARRAY extension r=kvark a=cwfitzgerald

This extends gfx-rs/wgpu#711 into wgpu-rs.

Notable changes: 
- Added an example showing off both this extension and the future descriptor indexing extension.
- Changed the framework so there is a static function showing what extensions you need. This is provided by the trait,, which defaults to no extensions, so existing examples and new ones don't have to care about extensions.
