Test GL YUV to RGB sampling of 601 and 709 colorspaces

Added tests to bind external GL YUV texture to OpenGL and
validate OpenGL rendered RGB colors. To bind YUV texture
to OpenGL, video with color bands is decoded to OpenGL
input surface.

The test vectors accessed from CtsMediaV2TestCases-2.1

Bug: 206034112
