ES31: Implement getMultisamplefv for D3D part.

Implement getMultisamplefv for d3d part.Because standard D3D sample
positions from https://msdn.microsoft.com/en-us/library/windows/
desktop/ff476218.aspx are fixed sample pattern,we put the sample
positions into a constant array in renderer11_utils.cpp with a
function to query it.

BUG=angleproject:1590
TEST=dEQP-GLES31.functional.texture.multisample.samples_*.sample_position
