Actionables from 2024-11-20 reading-club meeting

[jieyouxu]

• remove "identifiers in the compiler" (individual chapters for each ast/ir should just go in detail if warranted)
• move the stuff thats completely unrelated to source code repr to some new header such as "supporting infra" (and probably the closure expansion one to analysis since it basically just talks about type checking lol)
• Flesh out HIR chapter to go more in depth about how hir is structured and all its IDs #2143
• dont inline all the definitions of inline asm ast/hir/mir/whatever into the dev guide just link to it
• Talk about the async machinery, the key concepts, analysis, representations, etc. #2144

Two actionables were converted into separate issues.
