[wix-users] Downloading large payloads to drive with most free space

The Burn engine should be using the user's temp directory, not the system
temp directory.  I don't expect this behavior to change or be configurable,
if the user needs the temp directory on a larger drive then they can do

Starting in v3.9, the Package Cache location can be configured at the
system level -
Burn moves the packages into the package cache during execution even if
they won't be kept cached for security reasons, so this behavior isn't
going to change either.
