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)

1607: Fix Downlevel Vertex Stage Storage Buffer Check r=kvark a=cwfitzgerald
**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

DYNAMIC_INDEXING is checked by default, since WGPU doesn't allow
for any kind of specialization constants and constant indexing is
nigh useless.
STORAGE_RESOURCE_BINDING_ARRAY is enabled iff the device supports:
- both or neither of uniform and buffer arrays with dynamic indexing;
- both or neither of sampled and storage images with dynamic indexing.
NONUNIFORM_INDEXING is enabled iff for ALL types of descriptor arrays
*that are supported for dynamic indexing*, nonuniform indexing is
also allowed.
These flags have a limitation in that some platforms
(eg.
https://vulkan.gpuinfo.org/displayreport.php?id=11692#features_core_12)
may support a strange subset of those features (example device
supporting non-uniform indexing for textures and storage buffers,
but NOT for storage textures or uniform buffers). In that case feature
will be reported as missing, even though it is partially present.
In the author's opinion, this flag set is convenient for the
users to query; however, due to aforementioned limitations, it would be
desirable to obtain statistics about "edge-case" platforms and what
percentage of reports they comprise.

1559: Query support fixes r=kvark a=Wumpf
**Connections**
Fixes#1374 for master
If PR is accepted,I already have a fix for 0.9 which came out as a sideproduct: https://github.com/Wumpf/wgpu/tree/v0.9-fix-buffer-init-on-query-resolve
**Description**
Fixes:
* (affects master, v0.8, v0.9) query resolve operation not marking buffers as initialized
* (affects master) Broken query stride handling for Vulkan
* (affects master) Vulkan not advertising query support
**Testing**
* added new test
* mipmap sample
