Enable entities (elems, nodes, etc) to be flagged during RB mesh pre-evaluation

[apicard95]

• This update introduces a generic map in RB that can store various sets of dof_id_types. This can be used to identify elems, nodes, components and apply a specific treatment to those entities during EIM assembly.
• The map is stored in VectorizedEvalInput and transferred to RBParametrizedFunctions during mesh pre-evaluation (all qp data) using a unique_ptr.
• This map is then used to fill a second map that will store the same properties but only for EIM points. This second map is stored in RBEIMEvaluation and can be serialized and deserialized during the training.
• The "second" map can be accessed during EIM assembly using the EIMEvaluation.
