This is a first step towards auto-generating more EGL code. It
includes format handling for all the EGL parameter types, type
reinterpretation for EGL types using the "packed enum" handling,
and code refactoring to support the new consistent validation
entry point pattern.

Add the ability to release and reacquire the high-power GPU, and to
respond to changes in the active GPU. In Chromium, the GPU process can
not access the WindowServer. An external process must inform ANGLE
that the active GPU has changed, and that ANGLE should switch its
internal context to the new GPU.
Incorporates a couple of functions from WebKit, used with permission,
to effect this GPU switch.
A follow-on change in Chromium which uses these new APIs will make the
existing dual-GPU tests pass with ANGLE and the passthrough command
decoder.
Carry forward Chromium's workaround of disabling GPU switching on
older MacBook Pros to ensure stability.
Document the process of adding new EGL extensions to ANGLE.

eglGetMscRateCHROMIUM was added to EGL_CHROMIUM_sync_control based
on the original extension GLX_OML_sync_control. However, this new
function is not universally implemented. This CL moves it to a new
extension, EGL_ANGLE_sync_control_rate, and renames it to
eglGetMscRateANGLE.

When ANGLE is using the GL backend on GLX, we can expose
eglGetMscRateCHROMIUM via glXGetMscRateOML. Otherwise, this function
should return false.

This CL adds two new extensions:
* EGL_ANGLE_ggp_stream_descriptor:
Introduces a new attribute to CreateWindowSurface. Allows the app
to pass in a stream descriptor to VkCreateSurfaceKHR.
Mirrors VK_GGP_stream_descriptor_surface.
* EGL_ANGLE_swap_with_frame_token:
Introduces a new function 'eglSwapBuffersWithFrameTokenANGLE'. This
allows the app to pass a GGP frame token down to vkQueuePresentKHR.
Mirrors VK_GGP_frame_token.

For consistency, call these ANGLE "features", a subset of which may be
workarounds. Also, whether the feature is enabled/disabled should be
publically visible as "status".

Re-land fixes build to ensure commit_id is built before libEGL.
libEGL was implicitly loading libGLESv2 on startup. This is bad
because on platforms like Linux and Mac we could sometimes use the
incorrect rpath. This in turn meant we needed workarounds like using
"_angle" extensions to our shared objects to get the correct loading
behaviour.
Fix this by loading libGLESv2 dynamically in libEGL. We build the
loader automatically from egl.xml. The loader itself is lazily
initialized on every EGL entry point call. This is necessary because
on Linux, etc, there is no equivalent to Windows' DLLMain.
We also use an EGL.h with different generation options so we have the
proper function pointer types. A README is included for instructions
on how to regenerate EGL.h.
The entry point generation script is refactored into a helper class
that is used in the loader generator. Also adds the libGLESv2 versions
of the EGL entry points in the DEF file on Windows. This allows them to
be imported properly in 32-bit configurations.
Also fixes up some errors in ANGLE's entry point definitions. Also
includes a clang-format disable rule for the Khronos headers.
This CL will help us to run ANGLE tests against native drivers.
