service: Add buffer.clear_before_clone

Add a flag that causes the buffer to be cleared
prior to the Flush() that precedes a clone.
This is intended to be used together with transfer_on_clone,
so that if a data source takes too long to write data and
goes beyond the flush timeout, we don't mix old data and
new data on the next clone.
See go/clone-for-winscope
