You could try using a plugin to add a custom permalink base URL for media files, such as this one:

Attachment Slug

Then target the different link types purely with CSS:

.post-content a { /* any link or custom link */ }
.post-content a[href*="/media_base_url/"] { /* overrides for attachment links */ }
.post-content a[href*="/wp-content/uploads/"] { /* overrides for direct media links */ }

The only problem is with custom links, which are not targetable by themselves. In this case, you could use some JavaScript:

jQuery( function() {
jQuery('.post-content a > img').parent().addClass('media-link');
});
