 testsuite: Separate out Windows results for T5205

 This test seems to have much different allocation behavior on Windows
 and Linux.  Previously we had widened the acceptance window to 7% to
 accomodate this, but even this isn't enough any more. Instead of further
 widening the window let's just give an expected number for each
 platform. Really, this is precisely the issue with our performance
 testing model which I've been complaining about in #12758.

 Fixes test for #5205 on 64-bit Windows.

 Test Plan: Validate on Windows
