Fix support check in transform feedback tests

Fix support check in transform feedback tests

Vulkan transform feedback simple tests currently require
transformFeedbackRasterizationStreamSelect property for all test cases
using vertex streams other than zero. This CL changes the support check
to require the property only for test cases that rasterize vertex
streams other than zero. This CL also moves the support check to
checkSupport function which is called before initPrograms.

Affects:
dEQP-VK.transform_feedback.simple.*

Components: Vulkan

VK-GL-CTS issue: 3597
