Merge #18571: fuzz: Disable debug log file

fa69f88486e900aacf3fc768671f947927173226 fuzz: Disable debug log file (MarcoFalke)
fa0cbd48c418ec14e1d91bffea206bce20bd1e56 test: Add optional extra_args to testing setup (MarcoFalke)
fad4fa7e2fb95b7ced9007060ebfd0e8f181f5d8 node: Add args alias for gArgs global (MarcoFalke)

Pull request description:

  There are several issues with writing to a debug log file when fuzzing:

  * Disk access is slow, but fuzzing should be fast (Note: I could not verify this claim with data)
  * Disks have a limited size and will eventually run out of space, but fuzzing should run continuous

  Fix both issues by disabling the debug log file for fuzz tests
