Rename `StmtKind::Local` variant into `StmtKind::Let`

It comes from this [discussion](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Improve.20naming.20of.20.60ExprKind.3A.3ALet.60.3F).

Starting point was:

> I often end up looking at [ExprKind::Let](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir/enum.ExprKind.html#variant.Let) instead of Local because of the name. I think renaming it (both the `ExprKind` variant and the Let struct) to `LetPattern` or LetPat could improve the situation as I'm not sure I'm not the only one encountering this issue.

And then it evolved into:

> It's already `Expr::Let` instead of `StmtKind::Local`. Counterproposal: rename `StmtKind::Local` to `StmtKind::Let`.

The goal here is to clear this confusion.
