Pull request description:

  This is part of the coinstats index project tracked in #18000

  While the review of the new UTXO set hash algorithm (MuHash) takes longer recently #19328 was merged which added the possibility to run `gettxoutsetinfo` with a specific hash type. As the first type it added `hash_type=none` which skips the hashing of the UTXO set altogether. This alone did not make `gettxoutsetinfo` much faster but it allows the use of an index for the remaining coin statistics even before a new hashing algorithm has been added. Credit to Sjors for the idea to take this intermediate step.

  Features summary:
  - Users can start their node with the option `-coinstatsindex` which syncs the index in the background
  - After the index is synced the user can  use `gettxoutsetinfo` with `hash_type=none` or `hash_type=muhash` and will get the response instantly out of the index
  - The user can specify a height or block hash when calling `gettxoutsetinfo` to see coin statistics at a specific block height
