Polonius: Rename `parent` and `var_starts_path`

Polonius: emit initialization/move tracking facts
...
- var_starts_path
- parent
- initialized_at
- moved_out_at
This also switches to the intended emission of `var_drop_used` fact emission,
where that fact is always emitted on a drop-use of a variable, regardless of its
initialization status, as Polonius now handles that.

polonius: add generation of liveneness-related facts

Use new region infer errors for explaining borrows
...
This gives at least some explanation for why a borrow is expected to
last for a certain free region. Also:
* Reports E0373: "closure may outlive the current function" with NLL.
* Special cases the case of returning a reference to (or value
referencing) a local variable or temporary (E0515).
* Special case assigning a reference to a local variable in a closure
to a captured variable.

Rework checking for borrows conflicting with drops
...
Previously, we would split the drop access into multiple checks for each
field of a struct/tuple/closure and through `Box` dereferences. This
changes this to check if the borrow is accessed by the drop in
places_conflict.
This also allows us to handle enums in a simpler way, since we don't
have to construct any new places.

Don't reduce E0161 to a warning in NLL migrate mode
This error has been on stable for a while, and allowing such code cause the compile to later ICE (since we can't codegen it). Errors `box UNSIZED EXPR` with unsized locals because it's not compatible with the current evaluation order (create the box before evaluating the expressions).
