Adds upstream instance/adapter APIs. In dawn_native, the basic APIs
to get limits and properties are implemented, but requestAdapter and
requestDevice are not. In dawn_wire, nothing is implemented, but the
stub definitions are put in place, as well the mechanism to inject
WGPUInstance into the wire.
There is a lifetime concern with WGPUInstance and WGPUAdapter on the
wire in that we need to ensure that the client cannot free the
instance or adapter while they are in use. In the near term, this is
not a problem because Chromium will always hold ownership of the
instance and adapters outside of the wire - i.e. it won't inject and
then release ownership.

Change backend connection in Instance.cpp to store a bitset of
backends that have been connected. This lets us only connect to a
single backend if AdapterDiscoveryOptions are passed explicitly,
and track which connections have/have not been made. Later, we can
connect to the rest of the backends if more are requested.
This is part of some improvements to the existing code so we can
selectively discover adapters and control discovery of the
high-performance, low-power, and fallback WebGPU adapters.

Adds generated headers in dawn_native for object type tracking similar to that used in dawn_wire. Splits ObjectBase into ObjectBase and ApiObjectBase for clearly differentiation, and adds virtual function to identify the type of ApiObjects.

This CL adds two helpers for more ergonomic processing of
ChainedStructs.
1. FindInChain(): Iterates through the chain and automatically
casts the ChainedStruct into the appropriate child type before
returning.
2. ValidateSTypes(): Verifies that the chain only contains structs
with sTypes from a pre-defined set. This also allows the caller
to specify one-of constraints.
3. ValidateSingleSType(): Verifies that the chain contains a
single struct with a specific sType or is an empty chain. This
is a common case of |ValidateSTypes()| and is separated out as
a fast-path.

This is another step to implement webgpu.h swapchains, Surface is
essentially a union type of all the types of windows that can be used to
create swapchains.
Changes to allow implementing wgpu::Surface and test its creation are:
- Add GLFWUtils.cpp/.h/_metal.mm that contains helpers used to use
WebGPU with GLFW. This deprecates BackendBinding.h that will be removed
when the NXT swapchain is removed.
- Add a `dawn_use_x11` GN variable to factor all the places in BUILD.gn
where we checked whether we should use X11.
- Add a `supports_glfw_for_windowing` GN variable in the main BUILD.gn
file to control which configuration tests and samples using GLFW can be
built.
- Add a ObjCUtils.h to contain some ObjC functionality that we'd need
in files that otherwise would be C++ (so that they can be compiled on
all platforms).

This was used to make the distinction between native-only methods that
were those manipulating "natively defined" types, and the rest. Now that
all "natively defined" objects are "callback" instead this name didn't
make sense.
The only relevant thing is that in C there are the Reference and Release
methods that don't appear in dawn.json and shouldn't be exposed on C++
objects. Hence most of the native_methods() calls in the templates are
updated to be c_methods() calls except for the webgpu_cpp templates that
use type.methods directly.

webgpu.h is the "official" header for WebGPU in native and is being
developed in https://github.com/webgpu-native/webgpu-headers
dawn.h and dawncpp.h are changed to become webgpu.h and webgpu_cpp.h
respectively and use the new naming convention. New dawn.h and dawncpp.h
headers are created that just proxy the types, constants and functions
to their WebGPU counterpart.
Almost no naming change is done in Dawn in this commit, which help check
that the proxying headers work correctly. A couple changes were
necessary, in particular for tests of the internal of dawncpp.h, and a
workaround for a standard library bug for std::underlying_type was
removed because it is no longer needed and got in the way.
Finally since some templates were renamed to match the name of the file
they create instead of using the generic "api" name.
