Revert "Add more test_utils functions."

This reverts commit 5fcfcea4a9379633a83a67fc1d94938cb31f2a9c.

Reason for revert:
1 Test Suite(s) failed. angle_unittests failed because of:
TestUtils.RunApp on Linux CFI
https://ci.chromium.org/p/chromium/builders/ci/Linux%20CFI


Original change's description:
> Add more test_utils functions.
> 
> Includes methods for creating temporary files, deleting files, and
> reading files into a string. Also renames GetPathSeparator to mention
> it's only used for environment variables. Includes a new virtual type
> angle::Process that will be used to implement cross-platform async
> Process launching for tests. Also includes a way to specify a custom
> crash handler callback.
> 
> Also adds a few unit tests for the new functionality. They are disabled
> on Android because the functions are not needed by the new test runner.
> 
> Bug: angleproject:3162

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.
