util: Add fields to piglit_gl_test_config for listing supported GL flavors (v2)

This patch has 3 interrelated components.

1) Add the following fields to piglit_gl_test_config:
    supports_gl_core_version
    supports_gl_compat_version
    supports_gl_es1
    supports_gl_es2

These allow a test to specify what GL flavors under which it can run.  For
details, see the documentation for struct piglit_gl_test_config.

2. In tests/util/piglit-framework-gl, implement support for the new
fields.

3. In each GL test source, add one of the new fields to the
PIGLIT_GL_TEST_CONFIG_BEGIN/END block.

For GLES1 tests, add `supports_gl_es1 = true`. For GLES2 tests, add
`supports_gl_es2 = true`.  For desktop GL tests, add
`supports_gl_compat_version = 10`. For an explanation of why version 1.0
is used for desktop GL tests, see the documentation for
supports_gl_compat_version. No tests yet require a GL core context.

v2: Replace silly sum of booleans with a logical conjuction. For Anholt.
