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.

The OpenGL backend can't gather discover default adapters because it
needs getProc to do anything so we add DiscoverAdapters method to
Instance that takes backend-specific options.
dawn_native::opengl::CreateDevice is removed in favor of the adapter
path so OpenGLBinding is modified to create an instance locally. This is
only temporary until all backends support adapters, at which point a lot
of *Binding code will be factored.
Also contains a small fix for Result<T, E> with movable types.

New objects are introduced to control what happens before device
creation in dawn_native:
- Instance: a connection from the application to dawn_native that is
used for dependency injection and to discover adapters.
- Adapters: represents the possibility of device creation for a specific
(GPU, backend) pair.
- 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
ValidationTests to use the new Instance and Adapters concept and deal
with other backends later.
