[Files.app] Make getDriveEntryProperties() take multiple entries instead of single entry
Call of this private API has some overhead between C++ in the browser process and JS in a renderer process. This patch enables the method take a multiple entries so we can request properties of multiple entries with one call, and minimize a number of overheads.
This patch should change no functionality.
