Merge parametric_dimensions (PR #8083) to resolve build conflict

Both PR #7798 (ManualDrawingReference) and PR #8083 (parametric_dimensions)
independently added properties after entry #33 in Psets_BBIM_Annotation.ifc
and new BoolProperty declarations after `type_name` in prop.py and workspace.py
UI rows at the same locations.

Resolution: keep #8083's IDs (#34-#40) unchanged, renumber #7798's
IsManualDrawingReference and IsDocumentReference entries to #41 and #42,
update EPset_Annotation reference list accordingly, keep both UI rows,
and combine hotkey_S_A to use #8083's parametric-dimension routing
with #7798's "INVOKE_DEFAULT" argument for add_annotation.
