Revert "Disable stack sampling profiler under App Verifier"

This reverts commit 17178955.

Reason for revert: The CL this one was dependent on caused crashes and had to be reverted: crrev.com/c/1828234

Original change's description:
> Disable stack sampling profiler under App Verifier
> 
> The StackSamplingProfiler has been observed to cause crashes when
> running under Application Verifier, a Windows utility used to detect
> subtle programming errors. Samples collected by the
> StackSamplingProfiler while Application Verifier is running are unlikely
> to hold any value, as Application Verifier slows down execution
> significantly.
> 
> Because StackSamplingProfiler and Application Verifier are not
> compatible, this change detects whether Application Verifier is running,
> and does not start up StackSamplingProfiler if so.
> 
> This is not expected to impact data collection, as Application Verifier
> is used only by a few developers.
>
