fix(ui5-toolbar): restore item spacing in Horizon High Contrast themes (#13363)

The Toolbar-parameters.css base file (which defines --_ui5-toolbar-item-margin-right: 0.25rem and --_ui5-toolbar-item-margin-left: 0) was imported in the sap_horizon and sap_horizon_dark parameter bundles but was missing from sap_horizon_hcb and sap_horizon_hcw. As a result, toolbar items had no margin between them in Horizon HC themes.

Fixes: #13361
