Continued from part 1: #3231. Second step updating `docs/design/generics/details.md`. There remains some work to incorporate proposal #2200. - The biggest changes are incorporating much of the text of proposals: - #2173 - #2687 - It incorporates changes from proposals: - #989 - #1178 - #2138 - #2200 - #2360 - #2964 - #3162 - It also updates the text to reflect the latest thinking from leads issues: - #996 - #2153 -- most notably deleting the section on `TypeId`. - Update to rule for prioritization blocks with mixed type structures from [discussion on 2023-07-18](https://docs.google.com/document/d/1gnJBTfY81fZYvI_QXjwKk1uQHYBNHGqRLI2BS_cYYNQ/edit?resourcekey=0-ql1Q1WvTcDvhycf8LbA9DQ#heading=h.7jxges9ojgy3) - Adds reference links to proposals, issues, and discussions relevant to the text. - Also tries to use more precise language when talking about implementations, to avoid confusing `impl` declaration and definitions with the `impls` operator used in `where` clauses, an issue brought up in - #2495 - #2483 --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>

First step in updating
docs/design/generics/details.md. It incorporates changes from proposals: #989 #2138 #2173 #2200 #2360 #2964 #3162 , but there are still more changes from those proposals to be made.It also switches away from suggesting static-dispatch witness tables, and creates an appendix to describe that decision.
