Reset PHP’s peak memory usage when resetting scope for queue worker (#55069)

This is similar to the reset of the total query duration that is already
happening. PHP’s peak memory usage is another bit of global state is not useful
to keep in a long-running process handling individual self-contained jobs.

By resetting the peak memory usage for each executed job it becomes possible to
measure a given job’s maximum memory usage accurately, allowing to optimize
hardware resources, for example by placing individual jobs with a high-memory
usage into their own queue that is executed on a larger worker instance.
