rust errors: generate typed identifiers in each crate

Instead of loading the Fluent resources for every crate in rustc_error_messages, each crate generates typed identifiers for its own diagnostics and creates a static which are pulled together in the rustc_driver crate and provided to the diagnostic emitter.

There are advantages and disadvantages to this change..

Advantages

Changing a diagnostic now only recompiles the crate for that diagnostic and those crates that depend on it, rather than rustc_error_messages and all crates thereafter.
This approach can be used to support first-party crates that want to supply translatable diagnostics (e.g. rust-lang/thorin in https://github.com/rust-lang/rust/pull/102612#discussion_r985372582, cc @JhonnyBillM)
We can extend this a little so that tools built using rustc internals (like clippy or rustdoc) can add their own diagnostic resources (much more easily than those resources needing to be available to rustc_error_messages)

Disadvantages

Crates can only refer to the diagnostic messages defined in the current crate (or those from dependencies), rather than all diagnostic messages.
rustc_driver (or some other crate we create for this purpose) has to directly depend on everything that has error messages.
- It already transitively depended on all these crates.

Pending work

[x] I don't know how to make rustc_codegen_gcc's translated diagnostics work with this approach - because rustc_driver can't depend on that crate and so can't get its resources to provide to the diagnostic emission. I don't really know how the alternative codegen backends are actually wired up to the compiler at all.

I wonder if it would be possible to collect all the locale files into one directory in compiler/, maybe compiler/locales. Then the translation tool could be pointed at that, and you would only have one directory for each individual language, instead of one per crate. It would also help with ignoring the ftl files during a grep.

I don't have a particularly strong preference here. I don't know if there is a significant advantage to this. I haven't looked into how the translation tooling works to know whether a single directory will be easier or not, but it is very likely that only the original English will be in this repository regardless.

Also I wonder if instead of extending the driver, one could add another crate that collects all the translations, and have rustc_driver depend on that. Not sure about this one tho. Thoughts?

We could do this, it's really only an aesthetic consideration, so I don't have a strong opinion.

In both cases, will wait for others to weigh in.

I don't really know how the alternative codegen backends are actually wired up to the compiler at all.

I've looked at rustc_codegen_gcc and it seems to use the CodegenBackend trait through the codegen-backend feature. It seems that rustc_driver calls a function to generate a boxed trait object implementing that trait. Maybe that trait could be extended? cc @bjorn3

it is very likely that only the original English will be in this repository regardless.

Oh that changes a few things. In that case, the current state is okay. I wonder about the extra directory level, but that's only a papercut, as the disadvantage of it is quite minor (extra click in many IDEs). Some people might in fact prefer the locale/ dir over a raw file due to stylistic concerns.
