Returns the current timestamp in milliseconds using process.hrtime.bigint().
Narrows the absolute nanosecond value to a number, which loses precision
once it exceeds Number.MAX_SAFE_INTEGER (~104 days of uptime). For
benchmarking prefer hrtimeNowTimestampProvider, which keeps the bigint
until after the delta is taken.
