8b43ed5777 Rename timerUpdate() and timerGetRate() to timerUpdateClock() and timerGetClockRate(), because they both only apply to totalclock

222e593437 Change some clocks to support sub-tick precision using a new class, ClockTicks.
Using that higher precision, interpolate at a higher granularity.
Further, truncate the target interpolation time to vertical blank boundaries to avoid producing temporal artifacts.
Fix issues caused by interpolation calculations being handled differently in multiple places (and fix cases where smoothratios were being thrown away only to be redone without checking all proper conditions).
Ensure ClockTicks changes do not break other targets (EKenBuild, VoidSW), but note any interpolation there is not similarly updated.

0855428a0c timer.cpp: avoid using floating point arithmetic in timerUpdate()

021e1358c7 timer.cpp: improve cross-platform & cross-compiler issues relating to precision & period.
Handle timerlastsample such that we don't throw away time & run slow in certain cases.
Ensure when calculating n, we do the double division first before multiplying for sake of floating point precision.

c72a69ff6f This timing stuff actually works
It doesn't help when it turns out the compiler is broken and implementing std::chrono::high_resolution_clock as something that only counts in ms instead of properly aliasing it to std::chrono::steady_clock!
