Merge branch '303-tessellation-geometry-interaction-tests' into 'vulkan-cts-1.0-dev'

Geometry interaction tessellation tests

Ported from GLES 3.1

Some features were excluded:
- Transform Feedback related tests
- tests that required true runtime shader generation
  (because we need to support precompiled shaders)

Fixes #303

This depends on tessellation tests, implemented in !474

See merge request !501
