Bug 1860767 - Replace MOZ_ReportCrash call for AutoEnterOOMUnsafeRegi…

…on with fprintf. r=jonco, a=dsmith

According to bug 1859737, there are some issues with the stack dumping code on Windows
and the goal is to stop defining `MOZ_ReportCrash` in non-debug builds.
For `AutoEnterOOMUnsafeRegion` it seems simplest to do our own printf.
