The effect to the user is the same, the Dawn device gets lost. However
we need to make the difference internally because when the backend
device is lost we can clean up immediately. On the contrary on internal
errors, the backend device is still alive and processing commands so we
need to gracefully shut it down.

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.

DeviceLost is a better name because we don't have a "context" as in
OpenGL.

The error type will help distinguish between validation errors, context
losts and others which should be handled differently.
Take advantage of advantage of this to change DAWN_RETURN_ERROR to
"return DAWN_FOO_ERROR" to have the return be more explicit. Also
removes usage of DAWN_TRY_ASSERT for more explicit checks.

Linking against their .lib makes loading Dawn fail on systems that don't
have the DLLs. This happens for example on Windows7 that doesn't have
d3d12.dll. Instead we dynamically load functions pointers from these
DLLs at d3d12::Device startup.
