feat: improved error interface

[wseymour15]

Description

Changes to the MediaError class so we can expect a metadata property on this class, as well as creating a list of error types.

Specific Changes proposed

• Update of the MediaError class so jsdoc generates TS types for error types, as well as adding a new metadata property so we can give greater specificity to errors.
• Create a list of error types set on the video.js object to be reused throughout video.js and for developer usage.

Requirements Checklist

• Feature implemented / Bug fixed
• If necessary, more likely in a feature request than a bug fix
  • Change has been verified in an actual browser (Chrome, Firefox, IE)
  • Unit Tests updated or fixed
  • Docs/guides updated
  • Example created (starter template on JSBin)
• Reviewed by Two Core Contributors
