1704: Fix buffer memory initialization to use the tracker consistently r=kvark a=kvark
**Connections**
Depends on https://github.com/gfx-rs/naga/pull/1125
**Description**
Contains a number of dx12 fixes in addition to the buffer initialization fix.
The problem there was - we used the "pending writes" command buffer to initialize buffers, but also used the device's resource tracker and its state to figure out the transitions *after* a command buffer is merged its states.
**Testing**
Ran the examples on Vulkan.

1602: New DX12 backend (unfinished) r=kvark a=kvark
**Connections**
Continuation of #1471
**Description**
Mostly fresh implementation on DX12 backend for wgpu-hal
Core changes:
- texture usage is filtered before passing to `create_texture_view`, so that wgpu-hal can assume every bit is important.
- all the copies involving textures are limited to one array layer at a time
- remove render pass boundary usages
**Testing**
Examples (not running yet)

**Connections**
Fixes a bug in #1599. Also follows up on #1583 marking all of hello-compute as a failure.
**Testing**
Tests now pass on rpi4.

1599: Fix Limits for lava/llvmpipe and re-enable and re-work CI r=kvark,groves,wumpf a=cwfitzgerald
**Connections**
No longer fixes#1551.
**Description**
This PR has a couple things going on at once.
- Fixes limits for llvmpipe, lavapipe, and rpi4.
- Added a downlevel limit to express that RPI4 does not allow storage buffers in vertex shaders on GL.
- Added a `Limits::downlevel_default()` that takes minimum limits from GLES and adds some more documentation on how to choose limits.
- Moved all examples to the new downlevel limits
- Reworks CI to re-enable software testing and unify instructions.
**Testing**
It is

1592: Detailed limits check and error r=cwfitzgerald a=kvark
**Connections**
Related to #1590
**Description**
The old comparison "A < B" was simply wrong, because it would do every field in order and could bail out mid-way without reaching for all limits.
**Testing**
Untested
