Primary Key improvements

This CL changes @PrimaryKey sytax to disallow multiple fields with
@PrimaryKey annotations. Instead, it enforces using
@Entity#primaryKeys to declare composite primary keys.

This CL also fixes the inheritance rules around PrimaryKeys such that
we'll inherit primary key from super Entity / Pojo if the Entity itself
does not declare any primary keys. If the entity declares a primary
key, the parent key is dropped with a NOTE level log.
