  [flang] Define ERF, ERFC and ERFC_SCALED intrinsics with Q and D prefix (#125217)

`ERF`, `ERFC` and `ERFC_SCALED` intrinsics prefixed by `Q` and `D` are
missing. Codes such as `CP2K`(https://github.com/cp2k/cp2k) and
`TurboRVB`(https://github.com/sissaschool/turborvb) use these intrinsics
just like defined in the GNU standard and here:
https://www.ibm.com/docs/fr/xl-fortran-aix/16.1.0?topic=reference-intrinsic-procedures
These intrinsics are based on the existing intrinsics but apply a
restriction on the type kind.

- `DERF`, `DERFC` and `DERFC_SCALED` are for double précision only.
- `QERF`, `QERFC` and `QERFC_SCALED` are for quad précision only.
