lightbox_view: Fix media title update on change in title. 

Presently in a session when an image or video title is updated,
the same change is not reflected in the lightbox view of
them, until a new session is made.

This is because the metadata of the media is stored in Map
for the session with the preview_src as keys, and hence,
when title is changed the preview_src being same, the title
change is not reflected inside lightbox view.

This is fixed by modifing the asset_map (cache map) keys
from preview_src to an array of preview_src, and the media
title. Hence, when title is modified now, the keys won't map
to the existing value, and hence new metadata would be
shown.
A new function get_asset_map_key_for_media() introduced
to get the corresponing metadata from this asset_map
by passing in the prview_src and media elements.

Fixes #21311
