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.
