Fix the issue that LowCardinality of Int256 cannot be created.

Found by fuzzer.

While fixing this issue I discovered indecent code around TypeList:

• it was using abbreviations like TLUtils and I deeply hate abbreviations;
• TLIntegral confusingly consisted not only integer types, but also floating point types; and it did not consist all integer types.
