refactor(types): Type enhancements

[mister-ben]

Several changes for Typescript.

• Adds a jsdoc plugin to not break on @template {xyz} T. Replaces uses of T with Class.<xyz>
  • Used in component.js
• Adds definitions for ComponentOptions, SourceObject, PlayerOptions, MediaObject
• Removes further uses of ~ namespacing, which is valid jsdoc, but which tsc fails to understand
• Changes track kinds to simple union types. Change the existing definitions to enums so we can use them as object lookups without conflicting with the standard definitions.
• Use native TextTrackCue, TextTrackKind definitions.
• Exports Player, PlayerOptions and Plugin from video.js.
  • This makes it easier to add to the object than at present e.g. in a plugin to declare module 'video.js' { interface Player {
  • This sets a precedent - what else could/should be exported at this level? Should the names be more verbose?
• Adds additional jsdoc on for track and readyState in HTMLTrackElement, as tsc doesn't understand documentation for properties added with Object.defineProperties . Fixes HTMLTrackElement class provided missing two properties as stated in MDN #8959

This allows adding to the Player interface in plugins:

declare module 'video.js' {
  interface Player {
    touchOverlay: TouchOverlay;
    touchOverlayDirect: TouchOverlay;
    mobileUi: {
      (options?: MobileUiPluginOptions): void;
      VERSION: string;
    }
  }
}
