rustc: use a separate copy of P for HIR than for AST. Note: this currently includes/is based on top of rust-lang#61987. Like rust-lang#61968, but goes one step further and uses a separate `P<...>` for the HIR, with no `Clone`, or the ability to mutate after allocation. There is still `into_inner`/`into_iter`, but they're only exposed for `hir::lowering`, and they would take more work to untangle. r? @petrochenkov cc @rust-lang/compiler

This avoids synthesizing HIR nodes in
rustc_resolve, andrustc::hir::loweringpatching up the result after the fact (I suspect this is even more significant for @Zoxc's chages to arena-allocate the HIR).r? @oli-obk
