treewide: update dependencies

[lovesegfault]

This updates all of pixels's dependencies. Most importantly, it gets us winit 0.22 and wgpu 0.5.0.

This was done in a best-effort way, as I sometimes wasn't entire sure how to get things to work. There's a nasty transmute I want to get rid off, but couldn't figure out how. Figured I'd open the PR to get some ideas.

Here's the conway example running with the new deps:

[lovesegfault]

Alright, all warnings are fixed now :)

[parasyte]

What happened that made beryllium stop working with wgpu? And if all else fails, can we use the raw bindings (fermium) instead?

[lovesegfault]

@parasyte if you checkout this branch's first commit you can reproduce the issue:

error[E0277]: the trait bound `beryllium::window::gl_window::GlWindow: raw_window_handle::HasRawWindowHandle` is not satisfied

    |                      ------------------------------------- required by this bound in `wgpu::Surface::create`

error: aborting due to previous error

If someone can figure this one out then we don't need to nuke the SDL example :)

[lovesegfault]

Oh, wait, I think I figured it out!

[parasyte]

@lovesegfault It looks like you want to use create_raw_window instead of create_gl_window

[lovesegfault]

@parasyte Correct! Just fixed it :)

[parasyte]

It looks like MSRV in CI also needs to be updated to 1.40.0. https://travis-ci.org/github/parasyte/pixels/jobs/674268632

[lovesegfault]

@parasyte You may want to consider #61 before this PR, either way I'm fixing Travis :)

[parasyte]

It's on my plate to review.

This patch was needed to get minimal-sdl working. (Bonus: It works on macOS now! Fixes #47)

@parasyte Patch applied :)

[parasyte]

This is great! After merging, I'll followup by moving the examples to individual crates to fix the dependency bloat problem wrt. #62
