perf: add performance comparison tests for SymM vs MetaM (#11838) 
This PR adds performance comparison tests between the new `SymM` monad
and the standard `MetaM` for `intros`/`apply` operations.

The tests solve problems of the form:
```lean
let z := 0; ∀ x, ∃ y, x = z + y ∧ let z := z + x; ∀ x, ∃ y, x = z + y ∧ ... ∧ True
```
using repeated `intros` and `apply` with `Exists.intro`, `And.intro`,
`Eq.refl`, and `True.intro`.

**Results show 10-20x speedup:**

| Size | MetaM | SymM | Speedup |
|------|-------|------|---------|
| 1000 | 226ms | 21ms | 10.8x |
| 2000 | 582ms | 44ms | 13.2x |
| 3000 | 1.08s | 72ms | 15.0x |
| 4000 | 1.72s | 101ms | 17.0x |
| 5000 | 2.49s | 125ms | 19.9x |
| 6000 | 3.45s | 157ms | 22.0x |
