Add an optional size param to ApexFile::Open()
This can be used to open an apex file when it is not properly sized. For
example, it can be useful when apexd runs in guest OS and apexes are
passed as block-devices to share with the host OS. In such a case,
we need its actual size so that libziparchive's OpenArchiveFdRange can
open it without relying on the (possibly wrong) file size.
