Adds a mode to compaction that removes unused functions, global
variables, and named types and overrides. This mode is used
everywhere except the compaction at the end of lowering, where
it is important to preserve unused items for type checking and
other validation of the module.
Pruning all but the active entry point and then compacting makes
`process_overrides` tolerant of missing values for overrides that are
not used by the active entry point.
Fixes#5885
* [wgsl-in,ir] add support for parsing rust-style doc comments
* rename relevant items to `doc_comments` (or variations of it)
* address comments
* remove `next_until`
* rename `save_doc_comments` to `ignore_doc_comments`
* expand snapshot test and ignore blankspace when accumulating doc comments
* make tokenizer more straightforward

* Make wgpu-core's copy_buffer_to_buffer `size` parameter optional
* Make the copy size optional in more places
* Fix for webgpu backend
* [deno_webgpu] Support additional copyBufferToBuffer signatures
* Add changelog entry
* Add copyBufferToBuffer tests to CTS test list
(This doesn't actually enable the tests for the new overloads, because
of a different error reporting issue that affects many CTS tests
including these. But if you run the tests for the new overloads
manually, before and after the fix, you can see that the behavior has
changed.)
* Reproducible formula for vendoring modified webgpu-sys
Commit the updated vendor command in all the files for consistency.
* Potentially optimize `dot4{I,U}8Packed` on Metal
This might allow the Metal compiler to emit faster code (but that's not
confirmed). See
<https://github.com/gpuweb/gpuweb/issues/2677#issuecomment-1713292226>
for the optimization. The limitation to Metal 2.1+ is discussed here:
<https://github.com/gfx-rs/wgpu/pull/7574#issuecomment-2835464472>.
* [naga] Factor out new part of `put_block` on msl
CI on test failed because the latest changes to `put_block` made its
stack too big. Factoring out the new code into a separate method fixes
this issue.
* Rely on `libm` for a `no_std` alternative to `round_ties_even`
Update comments around `no_std` CI task
* Update Cargo.toml
* Feedback

Changes the MSL and HLSL backends to support writing only a single entry
point, and uses them that way in wgpu-hal.
This is working towards a fix for #5885.
* Increase the limit in test_stack_size
* [naga glsl-out] Differentiate between support for `std140` and `std430` layout, and emit `std140` in Uniforms when possible
* [naga glsl-out] Remove storage buffer std140 layout fallback, and error when we are unable to assign an explicit memory layout for uniform and storage globals

Closes#7481.
This implementation roughly follows approach 2 outlined in #7481, i.e.,
it adds a polyfill for the signed and unsigned dot product of packed
vectors for each platform. It doesn't use the specialized instructions
that are available for this operation on SPIR-V (with capability
DotProductInput4x8BitPacked).
