This patch adds the validation rules on the texture usage scope with
storage textures in one render pass.
1. Write-only storage cannot be used in combination with anything else
in the same render pass.
2. Sampled and read-only storage are allowed to be used in the same
render pass.
This patch also adds dawn_unittests to test the storage texture usage
scope in one render pass:
1. read-only or write-only storage only
2. read-only or write-only storage + sampled
3. read-only or write-only storage + output attachment
4. read-only + write-only
This patch also removes kWritableBufferUsages as it is not used in Dawn
at all.

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.

Overriding VK_DEFINE_NON_DISPATCHABLE_HANDLE changes the function
signatures of Vulkan functions, changing their ABI and making us
incompatible with real drivers. This removes that magic, and replaces it
with an explicit wrapper, VkHandle, which has much of the same
functionality as the original VkNonDispatchableHandle.
It adds definitions for dawn_native::vulkan::VkBuffer et al, which
shadow the native ::VkBuffer et al. This retains type safety throughout
the Vulkan backend without changing every single usage.
Notably, the following things had to change:
- An explicit conversion from VkBuffer* to ::VkBuffer* is needed for
arrays. This is implemented as a reinterpret_cast, which is still
safe as the new VkHandle still has the same memory layout properties
as VkNonDispatchableHandle did.
- When pointing to a VkHandle as an output pointer, it's now necessary
to explicitly get the native ::VkBuffer (via operator*) and point to

The way in which the Result class is used in Dawn can be fragile
with respect to memory management because the caller of AcquireError
must know they need to delete the returned pointer or a memory leak
will occur. We've had a couple of instances where developers have
accidentally left out the delete call and managed to get past code
review.
This CL changes the Result class so that it assumes the error is
allocated on the heap and forces the caller to use unique_ptr when
calling AcquireError.
