Add meson build
It is unclear to me whether adding a meson option is enough to resolve TODO: Add switch or condition to enable sync code so I kept that as-is for now.
Looks like the clang-format file is not applied treewide yet and I am not sure if formatted orage-about actually looks better. Maybe we can have ColumnLimit: 0?
Edit: I added the ColumnLimit: 0, the clang-format file is still not applied treewide but I think the changes here should be enough to pass git diff -U0 --no-color HEAD~4..HEAD | clang-format-diff -p1.
