Protect sensitive information for Amcrest cameras (#10569)

*  Creates a AmcresHub object to protect some private attributes on the logs

* Uses hass.data to pass AmcrestHub to components

* Prefer constants

* Removed serializer since it's using hass.data and simplified camera entity constructor

* small cleanup
