LibWeb: Implement WEBGL_debug_renderer_info extension

Browse Source 
This extension lets pages query the underlying GPU vendor and renderer
strings via UNMASKED_VENDOR_WEBGL / UNMASKED_RENDERER_WEBGL. Some sites
(e.g. yandex.com/maps) use it to decide whether to render vector tiles
with WebGL or fall back to raster tiles.

// NOTE: Original WEBGL_debug_renderer_info name is changed to title case,
// so it matches corresponding C++ class name, and does not require
// IDL generator to handle snake_case to TitleCase conversion.
// Having a different name is totally fine, because LegacyNoInterfaceObject
// prevents the name from being exposed to JavaScript.
