  Reland "Add more test_utils functions."
  
  This is a reland of 5fcfcea4a9379633a83a67fc1d94938cb31f2a9c
  
  Re-land uses static linking with angle_util. The root cause
  of the CFI error wasn't solved. Static linking works around
  the problem by not using any export rules.
  
  Second re-land fixes missing imports for libEGL and libGLESv2
  static varieties.
  
  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.
