Bug 1194555 - Part 3: Remove |getReportsForThisProcess| from the nsIMemoryReporterManager interface. r=njn
|getReportsForThisProcess| differs from |getReports| in that it is limited to current process and is synchronous. When asynchronous memory reporters are added the function will no longer be able tobe synchronous. There isn't much utility in only measuring the current process, so we can remove the function and switch existing users to |getReports|.
