examples/accel_perf: Add CRC-32C workload type

Browse Source 
This is more to exercise the various CRC-32C back ends than anything
else but will calc a CRC on the source data and if -y is
specified it will also calculate SW (ISA-L)f defined CRC-32C and
compare every operation against what the accel engine came up
with using whatever back-end was enabled.
