c38c4d32f4 Remove deprecated zero default size of buffer mapAsync
In this patch the deprecated usage of size=0 as default size is removed.
Using size=0 in buffer.mapAsync now result in a zero size mapping,
instead of the default size.

ff9a1f7b20 Adds/refactors destroy handling for Buffer and QuerySet.
The changes should pass through the destroy changes such that when the device is destroyed, the respective destroy functionality currently existing in the backends should be called.

For buffers, destroy no longer causes validation errors since even error buffers may need to be destroyed in the case of mappedAtCreation.

2a5b981a87 Deprecation of using 0 as default size in buffer mapAsync
For size parameter in mapAsync, use wgpu::kWholeMapSize rather than 0 to
indicate using the default size, i.e. remaining buffer size after
offset. Using size=0 is still available but will cause a deprecation
warning.

ed2b465f86 Report more detailed error information for the failures of mapAsync
This patch adds two new buffer map async status "destroyed before
callback" and "unmapped before callback" to replace the status "unknown"
so that the developers can get more details when meeting such errors in
the call of buffer mapAsync.

Note that this patch still preserves "unknown" as it is still being used
in Chromium.

0d52f800a1 Implement Buffer::MapAsync
MapAsync in dawn_native is fully implemented and only missing
a couple cleanups that can be done once MapRead/WriteAsync are
removed.

MapAsync in dawn_wire is left as a pure shim on top of
MapRead/WriteAsync and will be transitioned to its own commands
in follow-ups.

All MapRead/WriteAsync end2end and validation tests are duplicated
for MapAsync.

1318c603d9 Don't rely on null::Queue::Submit resolving mapping operations.
In the validation tests, we relied on Queue.Submit(0, nullptr) to
resolve mapping operations. This is fragile so we replace it with a
FlushMappingOperations() function that uses device.Tick() instead.

This allows removing the mapSerial argument from
Buffer::MapRead/WriteAsyncImpl (which was the actual goal of this CL).

dbf805fe8d Update GetMappedRange to not produce validation errors
GetMappedRange never produces errors and instead returns nullptr when it
is disallowed. When in a correct state, should return a valid pointer as
much as possible, even if the buffer is an error or if the device is
lost.

Adds tests for error buffers and device loss, and modify existing tests
to not expect a device error.

Also removes some dead code in the Vulkan backend and adds a fix for
missing deallocation of VkMemory on device shutdown.

8a437947a8 Introduce Device::GetDefaultQueue and deprecate CreateQueue
This makes all backends register the default queue at device
initialization time, so that the same queue is returned by
each call to GetDefaultQueue.

All usages of CreateQueue are replaced by GetDefaultQueue
except a couple ones that could use the queue initialized by
DawnTest::SetUp.

A deprecation warning mechanism is added so that users of Dawn
can now that they should upgrade their usage of the API. It also
comes with a backdoor so we can test that they are emitted.

New DeprecatedAPITests are added that will contain tests for
deprecated APIs, and will also check that deprecation warnings
are produced.

The special casing of GetDefaultQueue in the wire will be done
in a follow-up CL to ease the review. It happens to work through
the regular wire mechanisms at the moment but returns a different
object on each GetDefaultQueue call.

This removes the following for both Buffer and Texture:
 - The builder's SetInitialUsage
 - The object's FreezeUsage and TransitionUsage methods
 - The CommandBuffer Transition<Object>Usage methods

All samples and tests are simplified as a result. This also obsoletes
the UsageValidationTest which is removed.

Some validation was dependent on "current usage" and hasn't been
reintroduced for implicit transitions yet:
 - Buffers can be used while mapped
 - Swapchain textures can be used after they have been presented.

Validation for these will involve collecting all the resources used by a
command buffer and will be done in a follow-up patch.

b703def640 Add Device::CreateQueue() instead of the builder
We are changing all object creation to use descriptors but there is no
creation argument to pass for queue, so instead Device::CreateQueue
takes no argument.

e5ae3274a3 Make SetSubData take size in uint8_t not uint32_t.
Also change data pointer to uint8_t*.
Add a test for a non-aligned SetSubData().
Implemented on all backends.

cc0a54dbdb Implement MapWrite except in the wire.
Also this MapWrite doesn't zero out memory yet.

8565e0056a Rename "buffer map read status" to "buffer map async status"
This is in preparation of MapWriteAsync that will use the same status
enum.

2da19d5d6b Fix double MapReadCallback trigger when Unmapping in it.
When calling unmap on a mapped buffer for which the callback hasn't
fired yet, the callback should be called with UNKNOWN. The code marked
the callback as called only after calling it, causing problems with
re-entrancy where the callback would be called twice.

This could also get triggered by destroying the buffer inside the
callback.

Fix this in backend::Buffer and the WireClient and add test for both.

fffe6dfa16 Split backend/common in backend/ and common/
This directory used to contain both the state tracking code for the
backends, and the common utilities that could be used both by the
backends and the rest of the code. Things are now:

 - src/common is utility code for the whole repo
 - src/backend contains libNXT's code
 - src/utils is utility code that we don't want in libNXT

This commit also changes all includes to use global paths from src/
bacause it had to touch a bunch of #include statements anyway.
