Updated global attributes for auxiliary output as well as runs with WRF-CMAQ

Updates global attributes in auxiliary history files and separately for WRF-CMAQ

TYPE: bug fix

KEYWORDS: metadata, global attributes, auxiliary output, auxiliary history, WRF-CMAQ

SOURCE: Tanya Spero and Jeff Willison (U.S. EPA)

DESCRIPTION OF CHANGES:
Problem:
The suite of global attributes is incomplete in auxiliary history files. Notably, the precipitation tipping bucket is among the fields not included. Separately, there is no metadata in the header to indicate when WRF-CMAQ is used.

Solution:
Changes are introduced in share/output_wrf.F to expand the use cases to write the full suite of global attributes to the metadata of auxiliary output files. In addition, two global attributes are added to the output only when the WRF-CMAQ model is invoked (WRF_CMAQ_OPTION and DIRECT_SW_FEEDBACK).

ISSUE: Fixes #1476

LIST OF MODIFIED FILES: share/output_wrf.F

TESTS CONDUCTED:

1. Tests were conducted using the WRF model both with and without compiling with CMAQ. The base code was pulled from the branch "release-v4.6.0" on 8 May 2024. In both sets of tests on the EPA supercomputing system, an auxiliary output file was created in auxhist7. The global attributes were properly expanded to include the full suite of attributes in the auxiliary output file. The two new WRF-CMAQ coupled model attributes appeared when the WRF-CMAQ model was invoked.
2. Did not conduct Jenkins testing.

RELEASE NOTE: Expanded global attributes to the full suite for auxiliary history files. Also added two global attributes when the WRF-CMAQ model is invoked (WRF_CMAQ_OPTION and DIRECT_SW_FEEDBACK).
