io.elementary.{music,stylesheet,icons}: update to 7.0.0, granite7
https://github.com/void-linux/void-packages/pull/39219

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **YES**

For elementary-music I imported a patch from upstream (in the main branch, not in a release yet) that forces the GTK style to elementary. Otherwise icons and the application style is wrong.

granite7 is a separate new package because many applications still use granite (6) and granite7 uses GTK4 instead of GTK3
