Michael Pratt a40c7b1c77 runtime/pprof: run TestCPUProfileMultithreadMagnitude subtests separately
Currently TestCPUProfileMultithreadMagnitude runs two CPU consumption
functions in a single profile and then analyzes the results as separate
subtests.

This works fine, but when debugging failures it makes manual analysis of
the profile dump a bit annoying.

Refactor the test to collect separate profiles for each subtest for
easier future analysis.

For #50097.
For #50232.
