`TextEdit`: Change `margin` property to `egui::Margin` type (#3993) 

Despite their being an actual `egui::Margin` struct, Textedit has a
`margin()` builder function that supports only `Vec2` types and thereby
only symmetric margins. This PR changes the function to accept
`egui::Margin` type instead making it more congruent with overall egui
logic as well as supporting asymmetric margins.

P.S: I tried to run all checks but I had to modify `./rust-toolchain` to
1.67.0 to get the checks to run on macOS.
