Codechange: rework NewGRFProfiler to use ticks instead of calendar-days (#10815)

Browse Source 
We are planning to allow things like freezing the calendar, which
makes this variable a bit problemetic. So instead, suggest to the
user how many ticks there are in a calendar day, and let them figure
out how many ticks they want.

Additionally, use a TimeoutTimer for this, instead of an end-date
variable which is checked in an IntervalTimer.
