[Production/AQM.v7] Enhancing the EE2 Compliance to support the AQMv7 implementation

[JianpingHuang-NOAA]

Description

NCO raised a series of EE2 compliance that we need to address during the AQMv7 implementation. The issues are summarized as follows

1. Delete any util, scripts, modules and source codes that are not used by the AQMv7 operational implementation.
2. Remove any hard-code in the scripts or makefiles or any scrips
3. Remove any 0-sized fix file(s)
4. Replace "cp" with "cpreq" for any copying tasks
5. All jobs should fail with a "FATAL ERROR" printed and a descriptive message.
6. The forecast job fail on Feb 29, 2024 due to leap year issue.
7. Any other issues that do not meet NCEP implementation standards.
