Support CARBON_KIND with Any types (#6828)

Browse Source 
This uses the `CARBON_KIND_ANY(AnyImportRef, auto import_ref):` syntax
that seemed to be favored [on
Discord](https://discord.com/channels/655572317891461132/655578254970716160/1478486848207720478).

This converted uses in the `sem_ir` directory to show it works
initially, then added `check` for full coverage plus validating the
`SemIR::` namespace discard.

Note in inst_namer.cpp, AnyBindingPattern includes FormBindingPattern
which wasn't previously handled.

I'm disabling clang-format because I think it formats with readability
issues, e.g.:

```
#define CARBON_KIND_ANY_EXPAND_AnyBinding(X, SEP)                        \
  X(::Carbon::SemIR::AliasBinding)                                       \
  SEP X(::Carbon::SemIR::FormBinding) SEP X(::Carbon::SemIR::RefBinding) \
      SEP X(::Carbon::SemIR::SymbolicBinding)                            \
          SEP X(::Carbon::SemIR::ValueBinding)
```

Since `SEP` is typically a comma, it's also a nuisance to treat as an
argument to `X` (which could get better results).
