feat: support Gatsby-style directives in extensions

[yaacovCR]

BREAKING CHANGE: getDirectives now always return an array of DirectiveAnnotation objects

New function getDirective returns an array of args records for each use of the directive.

Note: this is true even when the directive is non-repeatable. This is because one use of this function is to throw an error if more than one directive annotation is used for a non repeatable directive!

See #2534
