view stats: Make CPU and GPU timestamps available (#1921)

Browse Source 
* view stats: Make GPU begin and end times available

* view stats: Make CPU start and end times available

* view stats: Remove redundant `gpuTimeElapsed`

Value can be derived by `gpuTimeEnd - gpuTimeBegin`

* view stats: Remove redundant `cpuTimeElapsed`

Value can be derived by `cpuTimeEnd - cpuTimeBegin`
