feat: test_extern command (#2970) 
This adds a `test_extern` command.

Usage:
```
import Lean.Util.TestExtern

test_extern Nat.add 17 37
```

This:
* Checks that the head symbol has an `@[extern]` attribute.
* Writes down `t == t'`, where `t` is the term provided, and `t'` is the
reference implementation (specifically, `t` with the head symbol
unfolded).
* Tries to reduce this to `true`, and complains if this fails.

Note that the type of the term must have a `BEq` instance for this to
work: there's a self-explanatory error message if it isn't available.
