Reduce dEQP-VK.pipeline.render_to_image allocs to within platform limits

These tests allocate an image of upto 25% of VkMemoryHeap heapSize and
should be limited to the value in
PlatformMemoryLimits.totalSystemMemory.

Component: Vulkan

VK-GL-CTS Issue: 2087

Affects:
dEQP-VK.pipeline.render_to_image*
