base: generalize ExecTicks to all messages with FmtTicksOff

If FmtTicksOff is given, ticks are disabled for all log messages.

The original motivation of this is to bring the implementation of native
traces closer to that of other traces to help refactoring done in future

One additional advantage of this is that sometimes we want to compare
traces of a given program under different conditions, so the start of the
ROI is different, and the different initial timestamp makes a diff
useless by showing differences on every line.
