WebGL "is resource" checking and object validation contains repeated …

Reviewed by Dan Glastonbury.

Checks of "isTexture()" and others, and webgl object validation has
following problems:
 - Uses inheritance for customizing behavior, forcing the base class
   have state which is not common to all subclasses
 - Has custom but similar code for each resource, with varying level
   of consistency (slight checking differences)
 - Has duplicated isContextLost() checks inside validation functions

Fix these by:
 - Using templates to implement the common logic for validation
   instead of using WebGLObject base class. This allows future changes
   to remove the virtualization, further simplifying the code.
 - Expose the differences in resource behavior in the `isUsable()`,
   `isInitialized()` methods in the resources.
 - Implement WebGLBindingPoint<T> template to implement "this object
   was bound" marker in a consistent, "provably" not missing any cases
   kind of way.
 - Removes unused WebGLRenderbuffer::isInitialized() and related
   WebGLFramebuffer::WebGLAttachment::isInitialized() code.
   The code was unused and appropriate to remove here due to the name
   clash with the added isInitialized().
 - Change validateWebGLObject object argument from pointer to object
   since it was always called with an existing object.
