ECC-2273, ECC-2274: Create definition files

[joobog]

Description

This pull request adds definitions for several new mineral dust aerosol species and introduces new parameters related to storm-relative helicity (SRH) and effective storm-relative helicity (ESRH) across multiple GRIB2 definition files. These changes enhance the representation of mineral aerosols and storm dynamics in the GRIB2 format, providing more detailed and standardised support for these meteorological and chemical fields.
