Add PIPELINE_OFFSET parameter to account for cumulative pipeline delay when multiple pack_networks are cascaded. Previously, control signals for later networks were not delayed to match the data pipeline latency accumulated from earlier networks, causing data corruption with larger channel configurations(in case of odd or non-power of two channel enables).

Add testbenches for 8, 32, 64 channel configurations to verify util_cpack2 behavior across various JESD204 use cases: -cpack_8ch_tb (M=8, S=4) -cpack_32ch_tb(M=32, S=1) -cpack_64ch_tb(M=64, S=1) Signed-off-by: Filip Gherman <filip.gherman@analog.com>

PR Description
High-speed JESD204B/C designs with many converters (high M) or many samples per converter (high S) face timing challenges in the cpack/upack routing networks. The long combinational paths through multiple MUX stages can become critical paths, limiting achievable clock frequencies.
This PR adds configurable pipelining support to util_cpack2 and util_upack2 cores to improve timing closure for high-speed JESD designs with large converter counts or high sample rates.
