* Added tests for texture zero init
sadly, they are typically passing even if texture zero init isn't doing its job
However, they form nice isolated examples for testing out texture initialization
It could be possible to dirty texture memory prior to ensure zero init did the job
* texture init tracker
* tracking texture init requirements for bind group, transfer and rendertarget
* texture clears for texture init
* queue submit
* write_texture
* Enforce presence of either render target or copy_dst flag
* clear render targets also with using buffer copies
enforce COPY_DST usage now on all textures
* adjust ImageSubresourceRange.layer_range calculation for 3D textures
init_tracker has now a `discard` function to get single data points back to uninitialized
use new standardized partition_point function
* track init state for discarded textures from renderpasses
missing:
* init on the fly if discarded is found within command buffer
* handle discarding only stencil or only depth
* added tests for zero init after discard
* tracking discarded surfaces now in separate struct, piping all inits through utility function
allows to resolve discard/init_action interactions
* Move various memory init code to separate mod
CommandBufferTextureMemoryActions is now fully encapsulated
* implemented discard init fixups for everything but renderpass
* render passes also cause now discard fixups
* fixup_discarded_surfaces takes now an iterator instead of Drain
* Add memory init test for discarding depth targets
* handle divergently discarded depth/stencil target
* comment & clippy fixes
* fix collect_zero_buffer_copies_for_clear_texture yielding block breaking copies
* [pr feedback] minor cleanup in zero_init_texture_after_discard, `use` hygenie
* [pr feedback] fix bug in ImageSubresourceRange range utils
* [pr feedback] fix texture tracker check, bundle transition_texture on init, cleanups
* Implemented drop for InitTrackerDrain
* remove incorrect comment about extents in add_pass_texture_init_actions
* Fix unit test & clippy issues in init_tracker
* enable CLEAR_COMMANDS feature for all adapters
* replaced fill_buffer with clear_buffer (minus variable value)
* Improve clear buffer/texture test
and remove unused clear-buffer.ron test
* renamed clear_image to clear_texture
* skeleton for new wgpu-hal clear_texture
* clear_texture implementation for vulkan
* clear_texture now restricts usage
* clear_texture implementation for dx12
* Implemented clear_texture for Metal backend
* Clean up GLES clear_buffer and leave note on how to implement clear_texture in the future
* fix linux compilation & formatting issues
* comment & namespace fixes
* Extent3d has now a simple mipmap calculating function
Fix incorrect use of texture.size in clear_texture for metal/dx12
Fix incorrect mip/layer ranges in clear_texture for metal/dx12
1525: Add Naga bypass to allow feeding raw SPIR-V shader data to the backend. r=kvark a=ElectronicRU
**Connections**
Fixes#1520 .
**Description**
While Naga checking is undoubtedly very useful, it currently lags behind
what is possible in SPIR-V and even what is promised by WGPU (ie binding
arrays). This adds an unsafe method to wgpu::Device to allow feeding
raw SPIR-V data into the backend, and adds a feature flag to request a
backend supporting this operation.
**Testing**
`texture_arrays` example is runnable now, which uncovers an additional bug in Vulkan backend - binding arrays are instead treated like sole bindings, and indices shift, too. Lots of errors from validation layer ensue.

- rename ShaderInput variants
- rename feature flag
- hard error on Metal backend trying to compile SPIR-V
- fix test failing because of feature flag bits changing
* Add command buffer fill buffer method
* Added test for buffer fill
* Added image clear + test
* image/buffer clear methods are now pure clear to zero
* fix cargo clippy & int type issues
* clear buffer alignment is now given by COPY_BUFFER_ALIGNMENT
* joined buffer/image clear player tests
* ImageSubresourceRange is now used in TextureViewDescriptor
- Rename `ColorAttachmentDescriptor` to `RenderPassColorAttachment`
- Rename `DepthStencilAttachmentDescriptor` to `RenderPassDepthStencilAttachment`
- Rename `attachment` fields on both attachments to `view`
* chore: validate offset + size in get_mapped_range
This commit introduces out of bounds & offset validation for
buffer_get_mapped_range, like described in the WebGPU spec. See
https://gpuweb.github.io/gpuweb/#dom-gpubuffer-getmappedrange.
Closes#818

The purpose of the PR is to support Naga modules everywhere.
As a requirement, it updates the gfx-rs version used.
Most of the logic is dedicated towards building a shader interface,
where previously we just used naga's IR. Now we have our own mini-IR.
* Replace &[T] in descriptor structs with Cow<[T]>
* Changed label fields to use Cow<'a, str>
* Deduplicate types across the tracing API
Introduce the ToStatic trait
* Deduplicate trace::RenderBundleDescriptor
* Remove ugly ToOwned bounds
* Simplifiy Action variants
* Make Clone bounds on type defs less verbose
* Fix a error in play.rs
* Remove ToStatic, and Make Action<'a> borrow descriptors instead
