[develop] Gaea pregenerated domain files path.

[christinaholtNOAA]

DESCRIPTION OF CHANGES:

Gaea only has TEST_PREGEN_BASEDIR set, and should also set DOMAIN_PREGEN_BASEDIR. Also, in the WE2E testing framework, run_WE2E_tests.sh sets GRID_DIR, SFC_CLIMO_DIR, and OROG_DIR using TEST_PREGEN_BASEDIR, but should also set DOMAIN_PREGEN_BASEDIR for consistency.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

@christinaholtNOAA These changes look good to me! I was also able to successfully run both the standard fundamental WE2E tests and the Jenkins fundamental tests on Gaea. Approving this work.
