Fix various Wformat warnings (#2135)

test_copy_1D.cpp: num_mip_levels is a cl_uint, so don't cast and just
print using `%u`.

test_pipe_info.cpp: arg_type_qualifier is a 64-bit wide bitfield, so
print in hexadecimal format using the correct length modifier.

test_device_partition.cpp: it is not clear what the bit width of
`cl_device_partition_property` should be, so cast the operands to align
with the format specifiers.
