[CMake] [MLIR] [Backport] Backport cmake from upstream to add missing mlir-headers dependencies (#1928)

Similar to #1927 , this allows generation of the missing mlir tablegen
targets without going through
```
$(ninja -C build_pilot -t targets all | grep IncGen | sed 's/:.*//')
```

Helpful to #1917
