[Piglit] [PATCH 18/24] arb_gl_spirv: add two linking tests for uniform multisample images

[Alejandro Piñeiro]

Use a uniform image2DMS and image2DMSArray. The latter related with
SpvCapabilityImageMSArray.

Note that those are linking tests, because although the specific
extensions are supported, in the practice multisampling is not allowed
as GL_MAX_IMAGE_SAMPLES is zero for most mesa drivers.
