[PATCH] D44570: [dwarf] Unify unknown dwarf enum formatting code

- changed "Unknown" to "unknown". I have checked GNU readelf output, they format unknown values completely differently (Unknown TAG value: 0x3e), so this doesn't make the compatibility story worse.
- added FORM, IDX, and AT format providers. These are the ones that are in use currently. Adding the rest is straight-forward.
- I did *not* add the ATOM format provider. To achieve this, we first need to create a separate enum for the DW_ATOM constants, so I left that for a follow-up patch.
