Correct Docblock
Simplify View blocks.

This set of changes breaks the existing behavior of blocks in a few
ways, but leaves us with a simpler and easier to reason about API. It
also solves weird behavior with prepend() where it wouldn't prepend at
all.

* startIfEmpty() is removed, as that behavior is not relevant when
  blocks always overwrite.
* append() and prepend() no longer have capturing modes. They can only
  be used to append/prepend content into blocks. The capturing mode of
  prepend never worked so I dobut anyone will miss this.
* Additional tests were added for the new behavior.

Refactor _eventManager accessors to Cake\Event\EventManagerTrait

Addresses issue #3592
Use a single method to set and get EventManager.
Always returns an EventManager, if none was previously set.
Cake\Utility\ObjectRegistry is aware of an optional EventManager.
Each class extending ObjectRegistry will need to use the trait.

Explicitly assign and access EventManager via protected field

This avoids issues with unit tests that mock the whole class,
causing eventManager() to always return null;
