Merge #14209/#17218: logging: Replace LogPrintf macro with regular function

Summary:
fae3fbd61a89c7a35bc0eda91b1df61371dc0936 logging: Replace LogPrint macros with regular functions (MarcoFalke)

Pull request description:

It is not possible to run the full test suite when configured with `--enable-lcov`, since logging is disabled currently so that "unnecessary branches are not analyzed". (See c8914b9dbbf6106dac3c62769f7ce3bacd8fbf9b)

Fix this instead by replacing the macros with functions.

Tree-SHA512: 101aa4f4a3ffcefc38faf70c9d3deb5fc63e0b11ca54a164d0463931c79eaf53ab0b0c6ae92a45355574e3b1d2c32233874a6b24293e7a09d188fc6698e212a5

Only LogPrintf() is replaced due to PR17218 reversing the change.

Backport of Core PR14209 and PR17218

Test Plan:

make check
./bitcoind -printtoconsole=0 -debuglogfile=0

Verify no logging information is printed.

./bitcoind -printtoconsole=0

Verify logging information is printed to debug.log file.

./bitcoind

Verify logging information is printed to console.
