macOS: Dpi overhaul (#997) (and rebase changes)

* WIP - Make EL2 DPI changes and implement on Windows (#895)

* Modify DPI API publicly and on Windows

* Add generic Position and make dpi creation functions const

* Make examples work

* Fix fullscreen windows not appearing

* Replace Logical coordinates in window events with Physical coordinates

* Update HiDpiFactorChanged

* Document to_static

* fix app_state errors

* fixes hidpi related errors in window_delegate

* fix bad merge

* dpi_factor edits in window_delegate

* fixes type and lifetime errors in window and window_delegate

* applies fmt

* complies with @aleksijuvani requested changes

* modifies Handler lifetimes

* fixes lifetime isues, adds propper handling for HiDpiChanged

* applies fmt

* restore original lifetimes

* solution is somewhere out there

* applies fmt

* pass as references

* resolves issue with HANDLER

* crate visible type error

* fixes visibility issues

* applies fmt

* deals with warnings

* simplifies new_inner_size setting algorthm

* moves proxy instead of referencing it and removes double deref from proxy.ns_window

* makes @Osspial tests (https://github.com/rust-windowing/winit/pull/997\#discussion_r301852354) pass

* complies with @aleksijuvani suggested changes

* makes max window size std::f32::MAX

Changes from rebasing:

* fixes compile errors

* applies fmt

* reimplements HiDpiFactorChanged after #1173 merge

* uses EventWrappers
