Bug 1777431 - Use the same default constants in both profilers - r=florian

Browse source 
The BASE_PROFILER_DEFAULT_...ENTRIES constants in BaseProfiler.h were smaller
than those in ProfilerControl.h, leading to a shorter profiling range in the
parent process!
Now these constants and some other shared ones are only defined in
BaseProfiler.h, and reused in ProfilerControl.h.

PROFILER_DEFAULT_DURATION was moved to where it's first used, and should one
day disappear (see bug 1632365).
