Allow for a single object upload for posts

[aashimawadhwa]

Is your feature request related to a problem? Please describe.
In the create post modal we have 2 different fields to upload video and image post.

Describe the solution you'd like
we want to make a single field that allows posting both images and videos through it, you can name the field as "Add media".

Additional context
make sure you manage the preview of the content within the model itself and manage the close preview state.
