[HIP] Fix return type for urKernelGetInfo UR_KERNEL_INFO_NUM_ARGS

The property should be of type size_t.

Note that we're removing a bunch of match lines for seemingly unrelated
properties, but in fact the CTS tests do not make use of the parameter
they claim, and in fact hard-code the UR_KERNEL_INFO_NUM_ARGS property.
