Title: Clarified WEBGL_lose_context error generation behavior

The WebGL spec indicates that getError may only return CONTEXT_LOST_WEBGL and NO_ERROR after a context loss, but the WEBGL_lose_context spec needs to generate errors to communicate issues losing or restoring a context. Added some text to clarify that this was explicitly allowed.
