Fix and re-enable EGLSyncControlTest.SyncValuesTest

It looks like the problem was not making the OS Window visible.
It turned out the previous version of the test succeeded only
when I ran angle_end2end_tests.exe with
--gtest_filter=EGLSyncControlTest.SyncValuesTest and failed
when I ran all tests, especially with --single-process-tests.

I tested the modified version of the test which repeated the
measurement 50 times and couldn't get a reliable test execution
until I figured out that back buffers were queueing and not
swapping successfully with the window being invisible.

This version works reliably when running all angle_end2end_tests.exe
on my workstation and on a test laptop, both running Windows 10,
with or without --single-process-tests.

ANGLE - Almost Native Graphics Layer Engine

The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.

ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.

Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
