autoloader moving those constants into a class makes them accessible to

The write-hook also is triggered for created files

Fix #8131

That method was moved to the external storage recently so
isn't needed here any more.

When using an external cache folder, it is automatically mounted in
FileSystem::initFileSystem so that any app can use it transparently
by creating a view on the "/$user/cache" directory.

Moved the mounting code for external storage from
OC\Filesystem::initMountPoint to files_external using the
post_initMountPoints hook
