Move check-cfg diagnostic logic into a separate file
as well as adding some triagebot mentions (for me) for check-cfg related files.

add myself to rotation
Won't have too much capacity, but I am able to contribute something. Will be rotating reviews if I run out of capacity :)
r? `````@ghost`````
`````@bors````` r+ rollup
This profile originally made sense when download-ci-llvm = if-unchanged
didn't exist and we had the bad tradeoff of "never modify or always
compile".
Thankfully, these grim times are over and we have discovered clean
water, so the only differentiator between the two profiles is the
codegen profile having LLVM assertions. Adding them doesn't cause that
much of a slowdown, <10% on UI tests from an unscientific benchmark.
It also had LLVM warnings when compiling, which makes sense for every
compiler contributor brave enough to compile LLVM.
The way I removed is by just issueing a nice error message. Given that
everyone with this profile should be a contributor and not someone like
a distro who is more upset when things break, this should be fine.
If it isn't, we can always fall back to just letting codegen mean
compiler.
Add myself to review rotation (and a rustbot ping)
I've still got a ~month of unemployment ( 🤞 ), so I'll put some of that time into reviewing.
Unrelatedly, I've now poked enough at match lowering that I want to follow what happens to it, so I added a rustbot ping.
Error codes are integers, but `String` is used everywhere to represent
them. Gross!
This commit introduces `ErrCode`, an integral newtype for error codes,
replacing `String`. It also introduces a constant for every error code,
e.g. `E0123`, and removes the `error_code!` macro. The constants are
imported wherever used with `use rustc_errors::codes::*`.
With the old code, we have three different ways to specify an error code
at a use point:
```
error_code!(E0123) // macro call
struct_span_code_err!(dcx, span, E0123, "msg"); // bare ident arg to macro call
\#[diag(name, code = "E0123")] // string
struct Diag;
```
With the new code, they all use the `E0123` constant.
```
E0123 // constant
struct_span_code_err!(dcx, span, E0123, "msg"); // constant
\#[diag(name, code = E0123)] // constant
struct Diag;
```
The commit also changes the structure of the error code definitions:
- `rustc_error_codes` now just defines a higher-order macro listing the
used error codes and nothing else.
- Because that's now the only thing in the `rustc_error_codes` crate, I
moved it into the `lib.rs` file and removed the `error_codes.rs` file.
- `rustc_errors` uses that macro to define everything, e.g. the error
code constants and the `DIAGNOSTIC_TABLES`. This is in its new
`codes.rs` file.
Remove myself from review rotation
Still willing to do reviews (and make it through my backlog), but I don't have the bandwidth to be on the rotation right now.
Don't add needs-triage to A-diagnostics
A-diagnostics is already labeled correctly thanks to the template and there usually isn't much to do on those issues, so it's fine to just add them to the pile.
