2f218e2b21 Implement upstream RequestDevice, add native-only CreateDevice
This CL implements RequestDevice and also has changes for
Dawn to internally use wgpu::FeatureName enums, instead of
strings. Some of the string handling is kept for now to
support the deprecated creation path. GetFeatureInfo is added
to the instance to get a name and description of the feature,
for reporting in about://gpu.

Dawn device toggles are now passed in an extension struct off
of the device descriptor. This is only supported in dawn_native,
and not dawn_wire, for now, since dawn_wire doesn't have a way
to serialize lists of null-terminated const char*.

To enable the client to check whether the toggle descriptor is
supported, a `dawn-native` feature is added which is supported
all the time with dawn_native, but not supported with dawn_wire.

Feature `dawn-native` also enables a synchronous version of
CreateDevice for convenience.

1f25ea94bb dawn_wire: Directly use the data in deserialized buffer when possible
This patch tries to use the data directly in deserialized buffer
when the data is "data-only" and doesn't affect the control flow instead
of allocating and copying into a temporary buffer. Due to the protection
of TOCTOU attacks, currently we only set "wire_is_data_only" on the
parameter "data" in Queue.WriteBuffer() and Queue.WriteTexture().

With this patch, the performance of dawn_perf_tests
BufferUploadPerf.Run/*_WriteBuffer_BufferSize_* with "-w" will
be greatly improved (~20%) when the upload buffer size is greater than
1MB.

ea3eee9885 resolver: Migrate validation to behavior analysis
Migrate some of the validation logic over to use the results of behavior
analysis.

The most significant changes are:
* Unreachable-statements now consider merge-points of control flow. For
  example, if all branches of a if-statement or switch-statement either
  return or discard, the next statement will be considered unreachable.
* Unreachable statements are no longer an error, but a warning. See
  https://github.com/gpuweb/gpuweb/issues/2378.
* Statements that follow a loops that does not break, or have a
  conditional will now be considered unreachable.
* Unreachable statements produced by the SPIR-V reader are now removed
  using the new RemoveUnreachableStatements transform.

Some other new changes include additional validation for the continuing
block for for-loops, to match the rules of a loop continuing block.
The new cases this validation is testing for are not expressible in
WGSL, but some transforms may produce complex continuing statements that
might violate these rules. All the writers are able to decay these
complex for-loop continuing statements to regular loops.

bf39c8fb19 sem: Replace SwitchCaseBlockStatement with CaseStatement
The SwitchCaseBlockStatement was bound to the BlockStatement of an ast::CaseStatement, but we had nothing that mapped to the actual ast::CaseStatement.
sem::CaseStatement replaces sem::SwitchCaseBlockStatement, and has a Block() accessor, providing a superset of the old behavior.

With this, we can now easily validate the `fallthrough` rules directly, instead of scanning the switch case. This keeps the validation more tigtly coupled to the ast / sem nodes.

fc5a7d414f Adds remaining setup logic to implement destroy in Device and ObjectBase.
- Renames some of the Device functions to be consistent with documentation
- Reverts change in https://dawn-review.googlesource.com/c/dawn/+/64820 for overloading mDevice == nullptr to determine if objects are alive because device is needed for error propagation. Instead, use list existence to determine if objects are alive
- Updates destroy api to return bool upwards in case we need to further process the extending objects
- Adds tracking functions in ObjectBase
- Adds final tag to all backend Device implementations
- Adds MoveInto LinkedList support to move list elements in O(1)

3f689a4c5a Rename "extension" to "feature"
This CL renames "extension" to "feature" to follow WebGPU. It still
supports both. A future Chromium CL will pick this change, then all
"extension" occurrences will be removed.

ba66295033 Improve validation errors, Part 1
Begin's using Abseil's string formatting and new error context tracking
to dramatically improve the usefulness of validation messages. In
addition to putting in place several utilities to enable better messages
this change also updates the BindGroup buffers bindings validation
messages as a test for the new mechanisms.

this will enable generating the exact upstream header.

922fce7295 Implement and test num_workgroups for all backends
For HLSL, use the new NumWorkgroupsFromUniform transform, and expose
the binding point to use for the generated uniform as a backend
option.

The MSL mapping is trivial, and it was already implemented for WGSL
and SPIR-V.

4cc4315d6c Allow array size to be a module-scope constant
Change ast::Array to use an ast::Expression for its `size` field. The
WGSL frontend now parses the array size as an `primary_expression`,
and the Resolver is responsible for validating the expression is a
signed or unsigned integer, and either a literal or a non-overridable
module-scope constant.

The Resolver evaluates the constant value of the size expression, and
so the resolved sem::Array type still has a constant size as before.
