[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.

Rollup merge of #62068 - ia0:fix_meta_var, r=petrochenkov 
Fix meta-variable binding errors in macros

The errors are either:
- The meta-variable used in the right-hand side is not bound (or defined) in the
  left-hand side.
- The meta-variable used in the right-hand side does not repeat with the same
  kleene operator as its binder in the left-hand side. Either it does not repeat
  enough, or it uses a different operator somewhere.

This change should have no semantic impact.
