MDL-61876 modules: cm_info::set_content can accept formatted text

Browse Source 
Allow modules to apply format_text() on user input before calling cm_info::set_content(). This is useful for
modules that add interactive content (for example, JS enhanced folder tree). Otherwise all javascript would
be removed if $CFG->forceclean is enabled.

Required changes in code:
* use new make_backup_temp_directory()
* Backup directory now can be outside of temp directory. Use make_backup_temp_directory($name) instead of
make_temp_directory('/backup/'.$name)
* Modules that provide their own interactive content and call cm_info::set_content() from [MODULENAME]_cm_info_view()
callback should format all user input and call set_content() with parameter $isformatted=true . Otherwise
scripts will be cleaned on the course page in case of $CFG->forceclean=1. See example in mod_folder.
