70102b7190 Add preliminary OpenGL ES and EGL support to Dawn.
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.

abdb566c30 Remove OpenGLBinding's dependency on glad
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.

90e594ee8b OpenGL: Implement the backend connection and adapter.
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.

dcb71a131c dawn_native: Factor getting procs into a single function.
Now the backends only expose the creation of devices. Getting the procs
is moved to DawnNative that will over time more backend-agnostic APIs.

196ade667f Make libdawn_native a shared library.
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.
