Problem/Motivation
#3347343: Continuation Add Views EntityReference filter to be available for all entity reference fields was getting overly complicated to get in in one issue. After discussion we opted to descope base fields and deal with non-base fields only first.
This issue is a follow-up to default entity reference base fields to use the entity_reference filter plugin provided in that issue.
Steps to reproduce
Attempt to use entity_reference for Comment Parent ID (an example entity reference base field from core)
Proposed resolution
Determine which entity reference base fields in Core do not provide viable alternatives and use the numeric filter (ie, many like uid already have viable alternatives)
Set the entity_reference field to be the default filter for those fields
Remaining tasks
For now everything (needs IS update)
User interface changes
Entity reference will be the default filter plugin for entity reference base fields
API changes
None
Data model changes
None
Release notes snippet
Base fields now default to using the Entity Reference Views filter plugin
