[mlir][ub] Add poison support to CommonFolders.h

Return poison from foldBinary/unary if argument(s) is poison. Add ub dialect as dependency to affected dialects (arith, math, spirv, shape).
Add poison materialization to dialects. Add tests for some ops from each dialect.
Not all affected ops are covered as it will involve a huge copypaste.
