feat: ApplyNewGoals config for apply
...
Lean.Meta.Tactic.apply now accepts an ApplyConfig argument.
`apply` now changes which metavariables are stored with choice
of the newGoals config.
This allows one to implement `fapply` and `eapply`.
An example of this is given in tests/lean/run/apply_tac.lean.
Closes #1045

fix: add expected type hint
...
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.

chore: style use · instead of . for lambda dot notation
...
We are considering removing `.` as an alternative for `·` in the
lambda dot notation (e.g., `(·+·)`).
Reasons:
- `.` is not a perfect replacement for `·` (e.g., `(·.insert ·)`)
- `.` is too overloaded: `(f.x)` and `(f .x)` and `(f . x)`. We want to keep the first two.

The new test exposes the problem fixed by this commit.
In the termination proof we have two `sizeOf xs` terms that are not
syntactically identical (only definitional equal) because the

fix: preserve arrow binder names and info at simp
...
We use the idiom `revert; simp; ...; intro` in a few places. Some of
the reverted hypotheses manifest themselves as arrows in the target.
Before this commit, `simp` would lose the binder names and info when
simplifying an arrow, and we would get inaccessible names when
reintroducing them.
