convert SFX_HINT to scoped enum

Notes

(*) In SC, BULK_DATACHANGED was or'ed into the hint id. Replaced with a
dynamic_cast check.

(*) In SC, removed the hint id field from ScIndexHint, no point in
storing the hint id twice

(*) Fold the SfxStyleSheetHintId enum into the new SfxHintId enum, no
point in storing two different hint ids

(*) In some cases, multiple #define's used to map to the same SFX_HINT
value (notably the SFX_HINT_USER* values). I made all of those separate
values.
