Dana Jansens 820e997261 Documentation update for require and extend impl as in interfaces and named constraints (#6240 )

Proposal [p5337](https://docs.carbon-lang.dev/proposals/p5337.html)
renamed and introduced new syntax for extending an interface or named
constraint with another.
- The `require` keyword can now be modified by `extend`, instead of it
being a separate thing altogether.
- Interfaces can `extend impl as I` to gain the members of `I` and
implicitly use them to implement `I`. Named constraints can not.

The `Identity` example is meant to not know anything about the type of
the object its passing through, but it ends up making a copy of it. Fix
the example to not by using a pointer.

Generics

This directory contains the collection of documents describing the generics feature of Carbon:

Overview - A high-level description of the generics design, with pointers to other design documents that dive deeper into individual topics
Goals - The motivation and principles guiding the design direction
Terminology - A glossary establishing common terminology for describing the design
Detailed design - In-depth description
- Appendix: Coherence - Describes the rationale for Carbon's choice to have coherent generics, and the alternatives.
- Appendix: Rewrite constraints - Describes the detailed rules governing rewrite constraints, and why resolving them terminates.
- Appendix: Witness tables - Describes an implementation strategy for checked generics, and Carbon's rationale for only using it for dynamic dispatch.
