Move extent copy and hash logic to a new file.
The SOURCE_COPY operation used to copy the source blocks one by one to
the target partition. This process is sub-optimal if there are several
consecutive blocks. This patch moves this copy and hash logic to a new
file and adds several unittests for it. The new logic copies in chunks
of up to 1MiB when the source and target data is contiguous.
BUG=b:34284069
TEST=Added unittests.
