Teach `SDNodeInfoEmitter` TableGen backend to process `SDTypeConstraint` records and emit tables for them. The tables are used by `SDNodeInfo::verifyNode()` to validate a node being created. This PR only adds validation code for `SDTCisVT` and `SDTCVecEltisVT` constraints to keep it smaller. Pull Request: https://github.com/llvm/llvm-project/pull/150125
