feat: add register_sym_simp command and SymSimpVariant infrastructure (#13034)
This PR adds the `register_sym_simp` command for declaring named
`Sym.simp`
variants with `pre`/`post` simproc chains and optional config overrides.

```
register_sym_simp myVariant where
  pre  := telescope
  post := ground >> rewrite [thm1, thm2] with self
  maxSteps := 50000
```

- `SymSimpVariant` structure storing `pre?`/`post?` syntax (elaborated
at use
  time in `GrindTacticM`) and `Config` overrides
- `SimpleScopedEnvExtension` for persistent cross-module variant storage
- `register_sym_simp` command syntax with `sym_simp_field` category
- Command elaborator with syntax quotation matching and duplicate field
detection
- `getSymSimpVariant?` lookup function
- `deriving Inhabited` on `Simp.Config` for extension support
