MDL-71956 core_h5p: Add more scenarios to can_edit_content
The method can_edit_content() now supports more scenarios where the H5P content can be edited: - Instead of supporting only mod_h5pactivity, now it supports any mod or block when the user has the addinstance capability. - If the component implements the can_edit_content method in the h5p\canedit class and it returns true. For instance, the mod_forum implements it and return true when filearea is post, if the user can edit the post where the H5P is.
