Align addition of a synthesized override of Base.Equals(Base? other) in records with the latest design. (#45601)

Related to #45296.

From specification:
If the record type is derived from a base record type Base, the record type includes a synthesized override of the strongly-typed Equals(Base other). The synthesized override is sealed. It is an error if the override is declared explicitly. The synthesized override returns Equals((object?)other).

This change also adjusts code-gen to properly compare EqualityContracts.
