This support was added in pydata/xarray#2844 and handles converting the grid_mapping variable to a coordinate in xarray itself, which was incompatible with some assumptions in parse_cf(). Add some handling for the case where the grid_mapping. Also add decode_coords='all' to our full test suite and adjust a few tests as necessary.

Description Of Changes
This support was added in pydata/xarray#2844 and handles converting the
grid_mappingvariable to a coordinate in xarray itself, which was incompatible with some assumptions inparse_cf(). Add some handling for the case where the grid_mapping. Also adddecode_coords='all'to our full test suite (parametrized) and adjust a few tests as necessary; this includes removing a test for not removinggrid_mappingattribute since that's not a universal truth any more (beyond our control).This is motivated by being compatible with rioxarray, which relies on
decode_coords='all'for its own projection handling, and can be used to load GOES data and do direct image remapping.Checklist
