LOG: [cmake] Pass LLVM_TABLEGEN_FLAGS to cross compile targets (#138086)

If ValueTypes.td contains conditional directives enabled by defs in
LLVM_TABLEGEN_FLAGS then native build tblgen and min-tblgen must be
built with matching flags.
This ensures the embedded types in TableGen are consistent with those
used for building tables.
