Meaningful Changes

• Remove disable-upgrade feature for 2.0 release
  • This feature is complicated to use in class-based elements, leading to "easy to write and hard to debug errors" in user code.
  • disable-upgrade may return in a a future minor release as a mixin or patch to customElements.define
• Fix warning logs for dyanmically bound functions
• Fix for observers firing before ready()
• Add new static API for creating property effects which mirror the instance versions
  • PropertyEffects.addPropertyEffect
  • PropertyEffects.createPropertyObserver
  • PropertyEffects.createMethodObserver
  • PropertyEffects.createNotifyingProperty
  • PropertyEffects.createReadOnlyProperty
  • PropertyEffects.createReflectedProperty
  • PropertyEffects.createComputedProperty
  • PropertyEffects.bindTemplate
