Replace mountType by volumeType on fileBrowserPrivate APIs.

This is API clean up. The mountType is being replaced by VolumeType. This CL
refactors private APIs about the flag.
Note that this is preparation to return Drive as a Volume.

BUG=279276
TEST=Ran unit_tests, browser_tests --gtest_filter="*FileSystemExtensionApiTest*:*FileManagerBrowserTest*:*FileBrowserPrivateApiTest*" and tested manually.
