fix: flush the CoreM and MetaM caches at modifyEnv
...
This fix may impact performance. Note that we don't need to flush the
cache if we are "adding" stuff to the environment. We only need to
flush the caches if the change is not monotonic. BTW, most of the
changes are monotonic. I think this is why we did not hit this bug before.
We may also move all these caches to an environment extension. It is
an easy way to make sure we preserve the cache when extending the
environment.
I tried a few benchmarks and did not notice a significant difference.

Other tactics (e.g., `simp_all`) may try to infer the type of the
proof, and `Nat.Linear.eq_of_toNormPoly_eq` has a messy resulting type.
