Deletion of Mountain giants

Comment: this is almost entirely |original research and much longer than the entry in the only cited source.  |Notability is also a concern since they have such minor apperences in Tolkien's works.  Unlike Hobbits say, I'd argue that these creatures don't deserve an article of their own, even if it's cleaned up and properly sourced
