Add test cases for bitwise and/or/xor for decimal type

[anshuldata]

• duckdb doesn't support bitwise and/or/xor for decimal type so not supported in duckdb dialect
• Currently I am focusing on Snowflake and Duckdb dialect so skipped other dialects for now.
• Set scale/precision based on Substrait spec (here) which is as follows for bitwise_and/or/xor :
  Input: (<P1, 0>, <P2, 0>) ==> Result: <max(P1, P2), 0>)

1. Build site is failing because we moved substrait submodule
2. Run tests with postgres/velox is failing because of "docker-compose: command not found". What is not clear to me why it suddenly started failing
   can you check these @richtia
