Migrate existing plugins only used in discover to the discover folder

• src/legacy/core_plugins/kibana/public/doc - the view when you click to see a single Elasticsearch doc entry Move doc, doc_viewer, context to discover folder #47436
• src/legacy/core_plugins/kibana/public/doc_viewer - contains the table, JSON view and 3rd party view, used by doc and discover Move doc, doc_viewer, context to discover folder #47436
• src/legacy/core_plugins/kibana/public/context - allows the user to view a single elasticsearch doc entry in context Move doc, doc_viewer, context to discover folder #47436
