[syclcompat][E2E] Skip case in math_vectorized_isgreater_test if fp16 unsupported (#14596)

The second test case in
sycl/test-e2e/syclcompat/math/math_vectorized_isgreater_test.cpp uses
vector of sycl::half, which requires devices to support aspect::fp16.
This commit makes the test skip this case if the device does not support
the aspect.
