Alona Enraght-Moony 5075931290 rustc_ast: Update P<T> docs to reflect mutable status. 
`P<T>` has implemented `DerefMut` since #54277. While this was lamented
at the time [1], rustc now relies on it extensively via the many
implementors of MutVisitor [2].

Updates the docs to reflect that `P<T>` is fundamentally mutable, and a
few other cleanups to make them nicer to browse.

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:
