This is enough to get all of the sample apps running on a conformant ES 3.1 implementation, such as ANGLE/Vk or NVidia's OpenGL ES Linux driver.
Implements a new opengl::AdapterDiscoveryOptionsES subclass to specify its creation at adapter discovery time.
Adds a "-b opengles" command-line flag to the code samples.
Asserts on a call to glShaderStorageBlockBinding() on ES.
Works around missing indexed draw buffers support by asserting when a non-0 color attachment is specified.
Works around missing glClearTexSubImage() by asserting. :/
These will likely require front-end validation.

This move all the OpenGL-specific code for swapchain handling in a new
NativeSwapChainImpl in the OpenGL backend so no code outside of
dawn_native needs OpenGL.

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.

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.
