editor: Add astrick on new line in multiline comment for Go, Rust, C, and C++ (#30808)

Add asterisk on new line in multiline comments for Go, Rust, C, and C++.
While `*` is entirely for style. There's no actual need for it. It can
be disabled from setting. More:

for Go, Rust, C, and C++. This can be disable by setting
