LibWeb: Refactor WebGL extensions to use a factory field and a hash map
Instead of manually listing out all the extensions which leads to a bunch of if cases that are more or less the same, lets replace all the fields with a hash map and introduces a factory field in the already existing list of extensions. This allows us to neatly compact the `get_extension` and makes implementing more extensions trivialy easy.
