Move shared file type images into chrome://theme/ scheme

These images are used by WebUI code (which uses 2x/ subdirectories for hi-dpi) and by C++ code (which uses the default_###_percent scheme). Move them to chrome/app/theme so that scaling will work in C++ code.

drive.png was unmentioned in the grd file. I added IDR_FILE_MANAGER_IMG_FILETYPE_DRIVE. Some uses of the images in CSS/JS use only the 1x versions. I left these as-is.


BUG=138965
TEST=Look at file manager and chrome://downloads in Linux chromeos build with --force-device-scale-factor=[12]
