615: Use General allocator at all times for now r=grovesNL a=kvark
In all user-managed resources, we don't have control of the lifetime. Since we don't know when it's released, we can't use any more specific allocator kind than `General`.
Previously, we assumed that buffers created for MAP_READ+COPY_SRC, for example, were one-time buffers created to copy data. However, there appear to be cases where they were used to fill data in once, and then persistently used as a copy source destination.
In the future, one WebGPU data transfer story is settled, we'll be able to use `Linear` kind again for all internally managed uploads. I.e. writeBuffer, writeTexture, and createBuffeMappedOnlyAtStart.

591: Warn when binding a buffer that is still mapped r=kvark a=almarklein
Fixes#510
I'd like to make more contributions wrt validation. Though I'm quite new to Rust, so let's start small :)
From the discussion in #510 I concluded that in this case the buffer has actually been dropped, does the error message make sense like this?
Do the messages logged with `log::warn`, end up in the same logging system as the layer validation messages? So a solution to get those messages into Python (for wgpu-py) would work for both kinds of validation messages?

582: Track pipeline layout lifetime r=grovesNL a=kvark
Fixes#580
This one is interesting: it's not instantly destroyed when dropped, like bind group layouts. And it's not tracked for GPU usage like the resources. It's somewhat in-between. We have the following classes of tracking now:
1. no tracking, destroyed on drop. Applies to: bind group layouts, adapters
2. only CPU-side tracking. They go to "suspected" list on drop of self or anything that can point to them. Applies to: pipeline layouts
3. full GPU tracking. They go to "suspected" list on drop, then get associated with active submission before destruction. Applies to: buffers, textures, views, bind groups, pipelines

581: Fix buffer unmap warning r=kvark a=kvark
It's more consistent if neither map_buffer or unmap_buffer care about the status.

570: Improve error message when bind group and bind group layout have different number of entries r=kvark a=HalfVoxel
Co-authored-by: Aron Granberg <aron.granberg@gmail.com>
When multiple "replace" style transitions are happening,
we weren't properly retaining the "first" state, which
is required for proper stitching of command buffers.
This logic is fixed and fortified with a new set of
"change" and "merge" tests in the track module.
We were improperly detecting if a swapchain image has already
been used by a command buffer. In this case, we need to assume
that it's already in the PRESENT state.
553: Fix order of maintenace between submission tracking and buffer mapping. r=kvark a=kvark
Fixes https://github.com/gfx-rs/wgpu-rs/issues/237
Logic needs to have the following order:
1. we first wait for the device to finish
2. then we move some tracked resources from per-submission lists into the "ready to destroy" or "ready to map" lists.
3. then we handle mapping, which goes through "ready to map" lists
4. then we destroy everything for realz that needs to be
That order got broken with #547
