Merge bitcoin/bitcoin#27556: wallet: fix deadlock in bdb read write operation
69d43905b7f1d4849dfaea1b5744ee473ccc8744 test: add coverage for wallet read write db deadlock (furszy)
12daf6fcdcbf5c7f03038338d843df3877714b24 walletdb: scope bdb::EraseRecords under a single db txn (furszy)
043fcb0b053eee6021cc75e3d3f41097f52698c0 wallet: bugfix, GetNewCursor() misses to provide batch ptr to BerkeleyCursor (furszy)
Pull request description:
Decoupled from #26644 so it can closed in favor of #26715.
Basically, with bdb, we can't make a write operation while we are traversing the db with the same db handler. These two operations are performed in different txn contexts and cause a deadlock.
Added coverage by using `EraseRecords()` which is the simplest function that executes this process.
To replicate it, need bdb support and drop the first commit. The test will run forever.
