Rollup merge of #93018 - pierwill:rm-unused-ord, r=davidtwco 
Remove some unused `Ord` derives based on `Span`

Remove some `Ord`, `PartialOrd` derivations that rely on underlying ordering of `Span`. These ordering traits appear to be unused right now.

If we're going to attempt to remove ordering traits from `Span` as suggested in https://github.com/rust-lang/rust/issues/90317#issuecomment-1013980591, we might want to slowly remove code that depends on this ordering (as opposed to the all-at-once approach in https://github.com/rust-lang/rust/pull/90749 and https://github.com/rust-lang/rust/pull/90408).

README.md

The rustc_ast crate contains those things concerned purely with syntax – that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).

For more information about how these things work in rustc, see the rustc dev guide:
