tsan: reset destination range in Java heap move

Switch Java heap move to the new scheme required for the new tsan runtime.
Instead of copying the shadow we reset the destination range.
The new v3 trace contains addresses of accesses, so we cannot simply copy the shadow.
This can lead to false negatives, but cannot lead to false positives.

Depends on D110159.
