Fix missing time for some script functions in profiler

Fixes the issue by adding a mechanism by which the functions that were
previously disappearing can be profiled too. This is optional with
an editor setting, since collecting more information naturally slows the engine
further while profiling.

Fixes #23715, #40251, #29049
