Bug 1962706 - Change memory budget for_device_loss threshold to 99. r=webgpu-reviewers,ErichDonGubler

We are first dividing the current usage by 100 then multiplying by the threshold. So we could run into a situation where current usage = budget but because we divided by 100 then multiplied by 100, current usage and budget might no longer be equal.
