Rename removeComponent method to hideComponent in EntityDisplayBase for clarity

Problem/Motivation

EntityDisplayBase uses the method removeComponent as a way to hide components from it's display, this is confusing language as "remove" is usually interpreted as a deletion, we've seen this confusion in #3303127: Determine which core config entity methods should be config actions

Proposed resolution

• Rename the method from removeComponent to hideComponent
• Update Tests
• Create BC w/deprecation notices
