356: Add generic ranges to buffer mapping api and make it safe. r=kvark a=lachlansneff
[Rendered](https://charted.space/notes/wgpu-rs/wgpu/struct.Buffer.html)
The safety issues with the current api (being able to unmap while still holding a slice to mapped data) are fixed by having `get_mapped_range` and `get_mapped_range_mut` return `BufferView` and `BufferViewMut`, which notify the buffer that those ranges are no longer being used when they're dropped. `Buffer.unmap` asserts that the list of mapped ranges is empty, therefore it is safe.

Main change here is the introduction of the Context trait.
The "direct" implementation of it goes straight to wgpu-core.
This commit also has small improvements:
- consuming command buffers on submit
- Instance type
- proper call to destructors
When looking into wgpu-rs as a replacement for WebGL I went to the
examples directory on GitHub to browse for a bit.
I wanted to see some of the examples at a glance without needing to
clone the repository.
This commit enables that by adding a README to each example with a
description of the example and screenshots / example output.
In a few cases the description is a bit redundant - but my hope is that
in the future we can improve all the READMEs.
Being a web API and thus very accessible, WebGPU could end up being many
people's first introduction to graphics programming so the lower we make
the barrier the better.

`File::create` isn't available on wasm, so we can't actually write the
output image anywhere unless we target something else as the file
system (e.g. local storage)
Remove odd patching matching
Replace std::sync::Mutex with spin::Mutex in GpuFuture
Reduce GpuFuture usage to one explicit allocation instead of two
Fix examples to poll the device in the background when using map_read or map_write
Remove device.poll from GpuFuture::poll and document future invariants
Massively simplify examples
Use Arc::clone(...) instead of arc.clone()
Switch println to log::info
210: Update WGPU deps to rev 08e8d406c1 r=kvark a=aloucks
I also moved the `path` chunks in `Cargo.toml` to a single `[patch]` section so that it's one block to commment/uncomment for local development.
