Dawn creates a keyed shared mutex for all wrapped resources and acquires
the mutex before the texture is used in an ExecuteCommandList call.
To coordinate with external clients, backend API has been extended
to allow clients to get and set the acquire key.
Pending and queue command lists have now been merged into one.
A future change will adjust GetPendingCommandContext to return a raw
command context without the need for error handling.

The functionality of the dawn_headers and libdawn targets are split into
the following targets:
- dawn_headers: the new version only exposes the "dawn.h" C API and no
longer includes the C++ API.
- dawncpp: the header and implementation of the C++ API that wraps the
C API. This is unbundled from the rest so the C++ API can be used
with libdawn_proc or other libraries implementing the C API.
- libdawn_proc: A DawnProcTable-backend implementation of the C API.
This is needed because in follow-up commit there will be three libraries
implementing the C API: libdawn_proc that trampolines where we want, and
libdawn_native/wire that don't have trampolines for better perf.

This patch implements "store and MSAA resolve" store operation on Metal
drivers that don't support MTLStoreActionStoreAndMultisampleResolve with
a workaround that does MSAA resolve in another render pass.
Driver workaround is one type of Dawn Toggles. Dawn Toggles will include
other optional optimizations and features that can be configured to use
or not when we create Dawn Devices.
As all Metal try bots don't need this toggle, to better test this
patch on the try bots:
1. We add the support of forcing enabling a workaround when starting an
Dawn end2end test so that we can test the workaround on the platforms
where the workaround is disabled.
2. We add an optional parameter DeviceDescriptor to CreateDevice() so
that we can custom the toggles the Dawn device should use.
This patch also adds the support of querying toggle details from Instance
and the names of the toggles in use from Device. These APIs are tested in
the Dawn unittests added in this patch.

- Instance: a connection from the application to dawn_native that is

- Adapters: represents the possibility of device creation for a specific

- BackendConnection: an internal object that standardizes the interface
between the frontend and backends.
The BackendConnection interface is implemented for the Null backend and
stubbed out in other backends. This allows this change to port the

WIN32 is defined by the SDK, but _WIN32 is defined by the compiler.
Since Dawn doesn't necessarily include <windows.h> everywhere dawn.h is
included, we should use _WIN32 (which will always be defined).
Also moves the TerribleCommandBuffer to utils:: because it isn't part of
the implementation of the wire, renames dawn::wire to dawn_wire, moves
src/wire to src/dawn_wire and puts the interface of dawn_wire in
src/include/dawn_wire.
The interface exposed by libdawn_native is declared in the new headers
living in src/include/dawn_native so that they both the users and the
libraries use the DAWN_NATIVE_EXPORT macros.
With this commit the Vulkan backend completely ignores the explicit
barrier commands passed from the frontend, and generates its own
pipeline barriers.
Right now it encodes each barrier just before the resources are used,
which is quite bad but will be optimized later.
This commit also makes the frontend command buffer validation perform
the checks necessary for implicit barriers (although they are redundant
with checks for explicit barriers) because the tracking can pre-compute
pass usage information that's useful for the Vulkan backend.
Tests for usage validation inside passes will be added once the concept
of transition is removed from the API.
Making all textures represented by pointers is a problem for Vulkan
where VkImage is a 64bit type and wouldn't fit in a pointer on 32bit
builds. Make texture contain on of each useful type so that each backend
can choose which one it wants to receive.
