[Fix, Test] (DirectGLES, DirectVulkan): advertise indirect draw capabilities accurately

Browse Source 
- advertise GL_ARB_draw_indirect when supported
- gate GL_ARB_base_instance on complete non-zero firstInstance semantics
- synchronize Driver POST reporting
- add capability and extension-advertisement regression tests
