Add icons for “M” (linear referencing) geometry types

[effjot]

Show geometry icons in locator search results for geometry types with “M” coordinate, e.g. LINESTRINGM.

LGTM

Note, when QGIS 3.28 will be minimum version, there is a builtin function in QGIS now https://api.qgis.org/api/classQgsIconUtils.html, I will make a patch in the plugin to use this function instead.

Hum, the geometry is a string, because we get it from ... d.geometry_type, ... FROM pgmetadata.export_datasets_as_flat_table('{locale}') d, not sure it's worth it to build the QgsMapLayer to use QgsIconUtils.

return QgsIconUtils.iconForWkbType(QgsWkbTypes.parseType(geometry_type)) should do the trick, but I haven’t tested it fully yet.

Thanks for checking.
I haven't tried, but just to keep notes : #161
