This reverts commit 8cc6205bf7.
Reason for revert: Graphite actually reuses the bind groups between
draw calls using different pipelines and this change prevents it
from happening.
Original change's description:

Normal behavior of ApiObjectBase's APIRelease() which only locks the
device when last ref dropped is not thread safe if the object is cached
as raw pointers by the device. Example of cached objects: bind group
layout, pipeline, sampler, shader module.
The following scenario could happen:
- thread A:
- shaderModuleA.APIRealease()
- shaderModuleA.refCount.Decrement() == true (ref count has reached zero)
- going to call shaderModuleA.LockAndDeleteThis().
- thread B:
- device.CreateShaderModule().
- lock()
- device.GetOrCreateShaderModule()
- shaderModuleA is in the cache, so return it.
- unlock()
- thread A:
- starting to call shaderModuleA.LockAndDeleteThis()
- lock()
- erase shaderModuleA from the cache.
- delete shaderModuleA.
- unlock()
This CL disables caching when ImplicitDeviceSynchronization is turned on
until we find a better solution.

1. Auto-generate mutex locking code in DawnNative's ProcTable's
functions. Using a mutex owned by the related Device.
- Unless the function/class has "no autolock" attribute (new) in
dawn.json. In which cases, no locking code will be auto-generated.
- Currently Instance, Adapter, Surface, Encoder classes and
Reference/Release method have "no autolock".
2. Added Feature::ImplicitDeviceSynchronization to enable Device's
mutex.
- If this feature is disabled, lock/unlock Device's mutex is no-op.
Auto-generated locking code will have no effect. This is the default.
- This approach is used instead of generating two sets of ProcTable
because it's cleaner and the internal code doesn't need to care about
whether there is a mutex being locked or not. Furthermore, if there
were two sets of ProcTable, and user used dawnProcSetProcs() to set
global ProcTable, it would affect all other modules using different
Devices. Even though those modules don't need thread safety.

This CL refactor the logic adapter creating device toggles set when
creating device and the way device holding its toggles. This CL also
introduce the concept "toggle stage", currently "device stage" only but
in future will add "instance stage" and "adapter stage" for instance and
adapter toggles. No changes on Dawn API.
More details:
1. Introduce `TogglesState` objects that represent the complete toggles
state of a device (and will used for instance and adapter in future).
2. When creating a device, adapter set up a TogglesState object for it
in `AdapterBase::CreateDeviceInternal` and
`Adapter::SetupBackendDeviceToggles`, no other place would change
the device's toggles state. This change simplify the logic.
3. Introduce the `ToggleStage` enum for every toggle and `TogglesState`
object. Currently we only have `Device` toggle stage, but in future
will have `Instance` and `Adapter` for instance and adapter toggles.

Add scaffolding for structured Dawn wire fuzzer.
This CL contains a basic fuzzer for Dawn wire server
that shows some simple design ideas:
1) A basic protobuf spec that is generated using dawn.json
2) conversion from protobuf message to a dawn wire server
command.
This is not the complete implementation and serves as a
foundation for the fuzzer so that subsequent CLs will be
easier to review.

Track reads and writes to pointer parameters for each function in the
Resolver, as well as accesses to module-scope variables. At function
call sites, check the root identifiers of each pointer argument to
determine if problematic aliasing occurs.
The MSL backend passes pointers to sub-objects to functions when
handling workgroup storage variables, which triggers the alias
analysis. Add a validation override for this scenario.

This CL starts adding the basics for an IR for Tint. The IR is
a lower level representation then the AST with several of the
restrictions removed. For example, the IR is mutable, is a DAG
instead of a tree, and removes a number of WGSL constructs to
simplify transforms.

These were quite spectacularly broken.
Also:
* Fix the definition of 'scalar' in `intrinsics.def`. This was in part why conversions were broken, as abstracts were materialized before reaching the converter builtin when they shouldn't have been.
* Implement `ScalarArgsFrom()` helper in `const_eval_test.cc`. This is used by the new conversion tests, and also implements part of the suggestion to improve tint:1709.

This extension adds support for the push_constant storage class such
that it can be tested with WGSL test files. The real goal is to allow
future transforms that will add push constants that the SPIRV writer
will output.
The extension:
- Adds the `chromium_experimental_push_constant` enable.
- Allows the push_constant storage class for global variables.
- Adds validation that the types are host-shareable for push_constant
variables, and that they don't contain f16 (must be 32bit types
only).
- Validates that at most one push_constant variable is statically used
per entry-point.
- Skips validation that the extension has been enabled if
kIgnoreStorageClass is used.
Tests are added:
- For parsing of var<push_constant>
- Caught a missing conversion.
- For each of the validation rules.
- For the wrapping of push constants in structs if needed by
AddSpirvBlockAttribute.
- For the layout and type rules of the storage class.
- For a shader with multiple entry-points using various push constants.
- Caught a missing reset of the previous push constant variable in
the validation check that at most one is used.
- Caught the missing wrapping in structs that had to be added to
AddSpirvBlockAttribute.
- Caught incorrect logic when adding diagnostics about the call
graph leading to the reference to push constants.

These were not marked as optional previously because it would mean that
C++ methods would look like void F(a = null, b, c) which is invalid in C++
because default arguments must be contiguous and at the end of the
signature.
This commit adds a special case when optional=true where no_default=true
still marks the argument as optional, but doesn't produce a C++ default
argument.
