Updates to ERF Driver for Multi-Level AMR, Radiation, and Misc.

[akashdhruv]

Summary

This PR introduces key enhancements to the ERF–Noah-MP coupled framework, including parallel I/O support, multi-level AMR capability, and coupling with the RRTMGP radiation model. The updates are mainly focussed on the driver side.

---

Key Updates

• Parallel NetCDF Output
  Implemented scalable I/O routines that allow multiple MPI processes to write NetCDF output concurrently, improving efficiency for large-scale simulations (drivers/erf/NoahmpWriteLandMod.F90).

• Multi-Level / Multi-Domain AMR Support
  Added support for multi-level adaptive mesh refinement (AMR) and nested domain configurations, enabling finer spatial resolution and more flexible simulation setups (drivers/erf/NoahmpIO_fi.F90).

• RRTMGP–Noah-MP Coupling Interface
  Introduced an interface to couple the RRTMGP radiative transfer model with Noah-MP, allowing interactive exchange of surface energy fluxes and radiative variables (drivers/erf/NoahmpIO.cpp).

• Exposed Wind Stress to ERF
  Updated (drivers/erf/EnergyVarOutTransferMod.F90) to expose wind stresses to ERF client.

---

Additional Notes

• Updated build configuration to support new AMR and I/O options.
• Verified compatibility with existing ERF runtime parameters and initialization routines.
• Preliminary tests confirm correct parallel I/O behavior and consistent radiative–land coupling results.

@akashdhruv I saw you included a few additional commits last week. Did you finish all the code updates? If so, I will start to review this next week and likely merge it in the next 1-2 weeks to the main branch. Because we have a few other Noah-MP updates coming up, I would like to get your updates in first before I make additional Noah-MP updates.

@cenlinhe Yes I am done, just updating documentation. Please go ahead and merge this.

[cenlinhe]

this PR updates the NoahMP-ERF interface driver, which looks good. The code developer provided the successful test run results in this PR, which looks reasonable.

@tslin2 Could you please take a look and approve this PR?
