3fbbb9a640 refactor: Get rid of more redundant chain methods
This just drops three interfaces::Chain methods replacing them with other calls.

Motivation for removing these chain methods:

- Need to get rid of findFirstBlockWithTimeAndHeight for #10102, which doesn't
  support overloaded methods
- Followup from
  https://github.com/bitcoin/bitcoin/pull/16426#discussion_r412487403
- phantomcircuit comments about findNextBlock test
  http://www.erisian.com.au/bitcoin-core-dev/log-2020-06-06.html#l-214

Behavior is not changing in any way here. A TODO comment in
ScanForWalletTransactions was removed, but just because it was invalid (see
https://github.com/bitcoin/bitcoin/pull/19195#discussion_r448020762), not
because it was implemented.

c0d07dc4cb wallet: Avoid use of Chain::Lock in CWallet::ScanForWalletTransactions
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change affects behavior in a few small ways.

- If there's no max_height specified, percentage progress is measured ending at
  wallet last processed block instead of node tip

- More consistent error reporting: Early check to see if start_block is on the
  active chain is removed, so start_block is always read and the triggers an
  error if it's unavailable

1be8ff280c wallet: Avoid use of Chain::Lock in rescanblockchain
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change only affects behavior in the case where wallet last block processed
falls behind the chain tip. The rescanblockchain error height error checking
will just be stricter in this case and only accept values up to the last
processed height

f7ba881bc6 wallet: Avoid use of Chain::Lock in listsinceblock
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change only affects behavior in the case where wallet last block processed
falls behind the chain tip. Previously listsinceblock might not have returned
all transactions up to the claimed "lastblock" value in this case, resulting in
race conditions and potentially missing transactions in cases where
listsinceblock was called in a loop like

c1694ce6bb wallet: Avoid use of Chain::Lock in importprunedfunds
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change only affects behavior in the case where wallet last block processed
falls behind the chain tip, in which case the "Block not found in chain" error
will be stricter and not allow importing data from a blocks between the wallet
last processed tip and the current node tip.

bf30cd4922 refactor: Add interfaces::FoundBlock class to selectively return block data
FoundBlock class allows interfaces::Chain::findBlock to return more block
information without having lots of optional output parameters. FoundBlock class
is also used by other chain methods in upcoming commits.

There is mostly no change in behavior. Only exception is
CWallet::RescanFromTime now throwing NonFatalCheckError instead of
std::logic_error.
