Subject: [PATCH] gnu: frescobaldi: Generate and wrap icons.

It is a following up 44db09e0d132b02c3ae10895406a6b7d3ece42df commit
where translation and metadata generation were removed while upstream
change the build logic; fixed wrap phase was re-introduced as well.

* gnu/packages/music.scm (frescobaldi)[arguments] <phases>: Add
'generate and 'wrap-executable.
[inputs]: Add qtbase, qtsvg, and qtwayland.
[native-inputs]: Add appstream, desktop-file-utils, and gettext-minimal.
