fa013664ae23d0682a195b9bded85bc19c99536e util: Add type safe GetTime (MarcoFalke)
Pull request description:
There are basically two ways to get the time in Bitcoin Core:
* get the system time (via `GetSystemTimeInSeconds` or `GetTime{Millis,Micros}`)
* get the mockable time (via `GetTime`)
Both return the same type (a plain int). This can lead to (test-only) bugs such as 99464bc38e.
Fix that by deprecating `GetTime` and adding a `GetTime<>` that returns the mockable time in a non-int type. The new util function is currently unused, but new code should it where possible.
