Expected behavior

getblockchaininfo.verificationprogress is 1.0 when it is done syncing

Actual behavior

The highest value that getblockchaininfo.verificationprogress gets to is something like 0.9999976273867589. As a result, we can not rely on this value to determine if syncing is complete. We can not rely on getblockchaininfo.initialblockdownload either due to #26432

To reproduce

Call getblockchaininfo on a synced node and observe that verificationprogress is < 1.0.
