Merge branch 'darincomeau/grids/add-trigrid-arrm-support' (PR #7442)

Add support for trigrid Arctic RRM

Adds grid alias, domain and mapping files for
arcticx4v1pg2_r025_ARRM10to60E2r1 resolution. All support files are
staged in public inputdata and world readable.

Adds new default 80 layer ncdata for arcticx4v1pg2 atmosphere mesh
(h/t @whannah1 ).

Fixes #7440
