[mlir] NFC: retire LLVM_Zero/OneResultOp from LLVM dialect ODS

These classes were initially introduced to factor out two common parts of LLVM
op definitions: the fact that they have no results or a single result of
LLVM_Type, and the default builders. Neither of the two parts is really
common anymore: many ops have more specific on the result type, and many ops
provide custom builders. The TableGen classes only add conceptual complexity
and make LLVM dialect definition dissimilar to other dialects. Remove them in
favor of explicitly specified builders (results are already specified).

Depends On D93329
