Increase the editor profiler frame history default and maximum limit
The new default value (1800) allows storing 30 seconds of profiling
at 60 FPS.

The new maximum value (10000) allows storing about 3 minutes of
profiling at 60 FPS.

The profiler graph will scale accordingly to the chosen setting,
so the default value is kept relatively low to prevent the graph
from looking too squished on narrow displays.
