performance.memory improvements

The performance.memory property is a non-standard API, seeing significant usage from some of our partners. With this change, if the renderer is locked to a site reported values will not contain coarse quantization and delay. This will allow developers to detect performance regressions from user data more easily because the memory measurements will be more accurate and can be taken more frequently.
