Andrew McCreight f6f2bd8f6e Bug 1655536, part 2 - Don't wait for memory reports from child processes that no longer exist. r=froydnj
This patch uses IPDL's return feature to ensure that the memory
reporter manager won't wait for a report from a child process
that has already exited.

This fixes a memory reporter hang that can happen if a child process
exits during a memory report, when the parent half of the actor is
being held alive. (If the parent half of the actor is not being held
alive, then mMemoryReportRequest will be naturally cleared when it
goes away.)

This was happening frequently on Windows Fission AWSY because that test
does a minimize memory right before it attempts to get a memory report,
and the preallocated content process exits when it sees a message to
minimize memory.
