c4a884d555 Trivial: Revert translated string change, clarify wallet log messages (Pierre Rochard)

Pull request description:

After multiple wallets became supported, wallet-related log messages became ambiguous as to which wallet they were being emitted by.

This pull request adds a `CWallet::WalletLogPrintf` function to be used when logging wallet-specific events. This function prepends the wallet's name to the log message and forwards it to `LogPrintf`

fixes #11317

Backport of Core PR12992 and PR13911
https://github.com/bitcoin/bitcoin/pull/12992/
https://github.com/bitcoin/bitcoin/pull/13911/

Test Plan:

arc lint --everything
make check
./bitcoind

Verify there is a wallet name attached to log files right after the init message: Loading Wallet ... line(s) like so:

[default wallet] nFileVersion = 200900
[default wallet] Wallet completed loading in              76ms

Add the following lines to anyfile:

LogPrint("Hello World");
LogPrintf("Hello World");
WalletLogPrint("Hello World");
WalletLogPrintf("Hello World");

After running the linter, there should be 4 different error messages with the following error message:

(LOGS1) Missing a newline at the end of the log message.
If this is deliberate, please use the `(Wallet)LogPrint*ToBeContinued()`
method instead.
