Add GeometryPointSize feature check

Add GeometryPointSize feature check

Some tests were using gl_PointSize without checking if the
shaderTessellationAndGeometryPointSize feature is supported and enabled.

This CL adds the feature checks to those tests. If the feature is not
supported/enabled, an alternative geometry shader code without
gl_PointSize will be used.

Affects:

dEQP-VK.glsl.*geometry
dEQP-VK.ycbcr.*geometry*
dEQP-VK.query_pool.*
dEQP-VK.transform_feedback.simple.streams_pointsize*

Components: Vulkan

VK-GL-CTS issue: 1763
