What is the motivation for this PR?
Fix test_ecmp_hash_seed_value failure on 202311
fix one function mistake in case.
remove internal and master from skip list, internal and master should support this case now
How did you do it?
Only check if sai_hash_seed_config_hash_offset_enable exists in config.bcm for 202305 branch, will skip this check for other branches.

How did you verify/test it?
run test_ecmp_sai_value against 202311.
