Skip fconvert16 if float16 not supported

The SPIR-V instruction test for float16 wasn't checking for the float16
capability correctly so didn't work properly on implementations that
don't support it.

Components: Vulkan
VK-GL-CTS issue: 1499
Affects:
    dEQP-VK.spirv_assembly.instruction.compute.opspecconstantop.fconvert16
