e4877b7e68 Rename AdapterBase -> PhysicalDeviceBase.
AdapterBase will become a (thin) wrapper class in an upcoming patch,
allowing a single PhysicalDeviceBase to be wrapped in multiple AdapterBases,
each with different toggles and flags.

For now, alias AdapterBase to PhysicalDeviceBase.

This patch disables resource sub-allocation for the 2D textures with

This CL make adapter base holds it supported features set as private
instead of protected and provide a method to set features enabled. This
CL also rename SetSupportedFeatures in null adapter to
SetSupportedFeaturesForTesting.
This is a pre-CL for implementing UseDXC as instance toggle, which may

c2657b21d5 Dawn: Promote DisallowUnsafeAPIs as instance toggle
This CL add Instance and Adapter toggle stage, and promote
DisallowUnsafeAPIs as an instance toggle, and can be required using
DawnTogglesDescriptor chained in instance descriptor when creating
instance. The instance's toggles state will get inherited to adapters
and devices it create. Related tests are implemented and updated.

Toggles inheritance can be overriden if not forced, so requiring
DisallowUnsafeAPIs when creating device is still available and working
like before.

Note that currently we don't have toggle of adapter stage, and can not
require toggles when creating adapter, until follow up CLs implement it.
Currently the toggles state of a adapter is simply inherited from
instance.

Dawn provides external semaphore service in static way by compiling

A better way is to select external semaphore in runtime.

This CL also removes "DAWN_USE_SYNC_FD" macro.

63b777b552 Dawn: Refactor device toggles
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.

f35c719054 Allow tolerance on compressed texture verification
Qualcomm GPUs are apparently decoding textures with a lower precision,
resulting in some of the rendered values when verifying the texture in
a test to be off by +-1 on any given channel. This change adds a
tolerance to those tests to allow a little wiggle room, since compressed
textures are inherently lossy anyway.

Allows Qualcomm GPUs to pass all compressed texture end2end tests.

7ca82ac4d0 dawn: Refactor device creation and add shader-f16 feature
This CL modifies the way adapter creating devices, adds `shader-f16`
feature, and deprecates the `dawn-shader-float16` feature which is no
longer used.
Details:
1. Parse the toggles chained with device descriptor in
`adapter::CreateDeviceInternal`, which are then used to validate
features requirement within `CreateDeviceInternal` and passed to device
constructor as initializer.
2. When creating device, validate features requirement in
`CreateDeviceInternal` with toggles known, make sure to fail the device
creation if a required feature is not supported by adapter or is guarded
by certain toggles which were not enabled/disabled. Feature ShaderF16
and ChromiumExperimentalDp4a are validated in this way. Unittest is
added to check creating devices with toggles-guarded features required.
3. Add `shader-f16` feature, which allow `using f16;` in WGSL code.
End-to-end tests are added to test a trival f16 WGSL shader could be
used if and only if the device has `shader-f16` feature.
4. Deprecate the `dawn-shader-float16` feature, which will be completely
removed after cleaning up Blink code.

6a9f9bd1ff Skip the check of maxFragmentCombinedOutputResources for Mesa llvmpipe driver
The Mesa Gallium llvmpipe driver is a software rasterizer that uses LLVM
to do runtime code generation. It seems to put incorrect value for
maxFragmentCombinedOutputResources, like we see on desktop GPUs.

Some relative values are as below.
vkLimits.maxFragmentCombinedOutputResources: 8
kMaxColorAttachments: 8
baseLimits.v1.maxStorageTexturesPerShaderStage: 4
baseLimits.v1.maxStorageBuffersPerShaderStage: 8

This CL will skip the check of this limit on llvmpipe, like we did for
desktop GPUs.
