Implement GL_EXT_multi_draw_indirect * Added the validation functions for multiDrawArraysIndirect() and multiDrawElementsIndirect() according to the specs. * Added generic implementation for the two functions that can be called by back-ends. * Added unit tests for the multiDrawIndirect functions. * Added flags for back-ends so they can enable the extension. * Minor cleanup in MultiDrawTest.cpp Bug: angleproject:6439 Change-Id: I4e5f1cab05c6de330aef82d115492dcc9d2fad44 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3276043 Commit-Queue: Amirali Abdolrashidi <abdolrashidi@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org>
