walletdb: Don't remove database transaction logs and instead error

Summary:
Instead of removing the database transaction logs and retrying the
wallet loading, just return an error message to the user. Additionally,
specifically for DB_RUNRECOVERY, notify the user that this could be due
to different BDB versions. This error is pretty much only caused by
compiling with a newer version of BDB and then trying to open the wallet
with a version compiled with an older version of BDB.

This is a backport of core#18907

Test Plan: ninja all check-all
