Move Pre-allocating up to position 0x[…] in […].dat log message to debug category.

After the cleanup of -debug=net log messages PR (#20724) was merged recently the console log now has very high signal to noise ratio. That's great! :)

This PR increases the signal to noise ratio slightly more by moving the most common remaining implementation detail log message (Pre-allocating up to position 0x[…] in […].dat) to the debug category where it belongs :)

Expected standard output from bitcoind (when in steady state) before this patch:

I find the latter alternative much easier to visually scan for anomalies (and more aesthetically pleasing TBH!).

Non-GUI users deserve nice interfaces too :)

Probably should be a separate PR, but might be worth thinking about moving the New outbound peer connected: ... (block-relay-only) messages to a debug category too, at least for the transient connections? (And perhaps add a new Replacing old outbound block-relay-only connection peer=X with peer=Y for the rare case when the new connection isn't transient because you drop one of your original block-relay-only connections instead). Those messages and the ones this PR already deals with look like most of the noise in my logs currently, at any rate.
