Auto merge of #60861 - Centril:let-chains-ast-intro, r=petrochenkov
[let_chains, 2/6] Introduce `Let(..)` in AST, remove IfLet + WhileLet and parse let chains
Here we remove `ast::ExprKind::{IfLet, WhileLet}` and introduce `ast::ExprKind::Let`.
Moreover, we also:
+ connect the parsing logic for let chains
+ introduce the feature gate
+ rewire HIR lowering a bit.
However, this does not connect the new syntax to semantics in HIR.
That will be the subject of a subsequent PR.
Per https://github.com/rust-lang/rust/issues/53667#issuecomment-471583239.
Next step after https://github.com/rust-lang/rust/pull/59288.
