Split media MDE toolbar from MDE toolbar

Fixes #17348

[hishamco]

<script at="Foot" asp-name="MediaFieldAppInitializer" depends-on="media">
    initializeMediaApplication(false, '@Url.Action("MediaApplication", "Admin", new { area = "OrchardCore.Media" })', '@Context.Request.PathBase.ToString()');
</script>

This will be broken if the media feature is disabled

I think this will be fixed by the new Media Gallery. We need to inject this media icon item differently simply. Not having 2 different scripts.

I'll defer to @Skrypt on assessing what we should do here. Also, note two things:

• Fix the Markdown editor's implicit dependency on Media #17348 (comment)
• The build is failing.

While @Skrypt will address this in his PR, I will not go further unless his PR takes time

[Skrypt]

I will fix it in the new Media gallery and come back here to report what I've found keep the PR open
