Initial (incomplete) implementation of transmutability trait. This initial implementation handles transmutations between types with specified layouts, except when references are involved. Co-authored-by: Igor null <m1el.2027@gmail.com>

[dependencies]
Clean up `rustc_*/Cargo.toml`. - Sort dependencies and features sections. - Add `tidy` markers to the sorted sections so they stay sorted. - Remove empty `[lib`] sections. - Remove "See more keys..." comments. Excluded files: - rustc_codegen_{cranelift,gcc}, because they're external. - rustc_lexer, because it has external use. - stable_mir, because it has external use.

rustc_transmute: Directly use types from rustc_abi

rustc_abi = { path = "../rustc_abi", optional = true }
Convert `TypeVisitor` and `DefIdVisitor` to use `VisitorResult`

transmutability: Mark edges by ranges, not values In the `Tree` and `Dfa` representations of a type's layout, store byte ranges rather than needing to separately store each byte value. This permits us to, for example, represent a `u8` using a single 0..=255 edge in the DFA rather than using 256 separate edges. This leads to drastic performance improvements. For example, on the author's 2024 MacBook Pro, the time to convert the `Tree` representation of a `u64` to its equivalent DFA representation drops from ~8.5ms to ~1us, a reduction of ~8,500x. See `bench_dfa_from_tree`. Similarly, the time to execute a transmutability query from `u64` to `u64` drops from ~35us to ~1.7us, a reduction of ~20x. See `bench_transmute`.

Revert introduction of `[workspace.dependencies]`. This was done in #145740 and #145947. It is causing problems for people using r-a on anything that uses the rustc-dev rustup package, e.g. Miri, clippy. This repository has lots of submodules and subtrees and various different projects are carved out of pieces of it. It seems like `[workspace.dependencies]` will just be more trouble than it's worth.

transmutability: uninit transition matches unit byte only The previous implementation was inconsistent about transitions that apply for an init byte. For example, when answering a query, an init byte could use corresponding init transition. Init byte could also use uninit transition, but only when the corresponding init transition was absent. This behaviour was incompatible with DFA union construction. Define an uninit transition to match an uninit byte only and update implementation accordingly. To describe that `Tree::uninit` is valid for any value, build an automaton that accepts any byte value. Additionally, represent byte ranges uniformly as a pair of integers to avoid special case for uninit byte.
