render_literal_bindparam() naively calls cached_bind_processor

[Mike Bayer]

I think we need a new method on type that's specific to rendering a type for literal SQL. At the moment, a string type on an encoding backend can pass in a bytes into render_literal_value (see test.sql.test_types:EnumTest.test_mock_engine_no_prob using Oracle backend on python3). We're working around this by re-decoding the bytes in the method, but more elaborate bind processor schemes will need to be aware of literal SQL and naturally this should be type-based in any case.

initial idea is in the ticket_2838 branch at bc5834d6431663ad2a03677af87dd96a8de923e1. we'll move the whole concept of literal bind rendering into the type system.

the String type will also need to determine if encoding is needed here.
