make the dataflow / mir-borrowck types carry a 'tcx lifetime

Also, factor out `do_mir_borrowck`, which is the code that actually
performs the MIR borrowck from within the scope of an inference context.
This change should be a pure refactoring.

`EndRegion` do not always correspond to borrow-data entries
Remove assertion that the argument to every `EndRegion` correspond to some dataflow-tracked borrow-data entry.
Fix #44828

For box expressions, use NZ drop instead of a free block
...
This falls naturally out of making drop elaboration work with `box`
expressions, which is probably required for sane MIR borrow-checking.
This is a pure refactoring with no intentional functional effects.

Turn `elaborate_drops` and `rustc_peek` implementations into MIR

Rewire things so `rustc_driver` uses the `ElaborateDrops` from
