feat: implied or external fragments, for #612

[acao]

allows external, implied fragments in autocompletion, validation, and operation execution. resolves #612

• adds this capability to monaco-graphql, codemirror-graphql, and graphiql
• provide an array of fragment definitions or a string containing fragment definitions
• only fragments you use are added in operation exec, thus in fetcher params as well
• still only shows valid autocomplete entries for fragment spread
• also exposes a documentAST of the current operation in onEditQuery and in the fetcher
• concatenate fragments in codemirror for linting

todo:

• code completion for GraphiQL, monaco-graphql, codemirror-graphql
• operation execution
• validation
• test coverage

@sgrove note this change introduces use of internally and exposes a single AST document, that only changes on editor or props-driven query change. it's been added to onEditQuery and to the fetcher params. anywhere else that something like this would be handy for your plugin needs?
