Unable to use Mockito 3.1.7+ with Android on lower SDK devices.

Reason:

• FR: add Mockito.timeout(java.time.Duration) and after(java.time.Duration) #1815
• Add Duration overloads. Fixes #1815 #1818

https://developer.android.com/reference/java/time/Duration <-- This was not added to Android until SDK 26.

https://developer.android.com/about/dashboards <-- here are some distribution stats. Most noticeably, this would impact testing for 70% of the market and is not ideal.

java.lang.NoClassDefFoundError: java.time.Duration
