tests: Add integration with Khronos CTS OpenGL runner

This adds support for running Khronos' deqp-based conformance suite for
OpenGL with piglit.

This commits renames PIGLIT_CTS_BIN / PIGLIT_CTS_EXTRA_ARGS envvars to
PIGLIT_CTS_GLES_BIN / PIGLIT_CTS_GLES_EXTRA_ARGS respectively.

v2 (Dylan Baker):
  - Use cts_gles and cts_gl
  - Rename PIGLIT_CTS_foo to PIGLIT_CTS_GLES_foo

+"""Piglit integration for Khronos CTS tests.
+
+By default this will run GLES2, GLES3, GLES31, and GLESEXT test cases. Those
+desiring to run only a subset of them should consider using the -t or -x
+options to include or exclude tests.
+
+For example:
+./piglit run cts_gles -c foo -t ES3- would run only ES3 tests (note the dash to
+exclude ES31 tests)
+
+This integration requires some configuration in piglit.conf, or the use of
+environment variables.
+
+In piglit.conf one should set the following:
+[cts_gles]:bin -- Path to the glcts binary
+[cts_gles]:extra_args -- any extra arguments to be passed to cts (optional)
+
+Alternatively (or in addition, since environment variables have precedence),
+one could set:
+PIGLIT_CTS_GLES_BIN -- environment equivalent of [cts_gles]:bin
+PIGLIT_CTS_GLES_EXTRA_ARGS -- environment equivalent of [cts_gles]:extra_args
