Revert "Disable more CopyBetweenWindows tests."

This reverts commit 5a12eea7.

Reason for revert: The fixture is a timeout/pass in DEBUG only, but 
this CL disabled test on all bots: RELEASE/MSAN/ASAN.  So can we
please not do that?  Thank you.

Original change's description:
> Disable more CopyBetweenWindows tests.
> 
> Similar to copyBetweenWindowsDriveToUsb, copyBetweenWindowsLocalToUsb
> and other related tests are also flaky. Disable them all.
