lsp format

[Decodetalkers]

Since there is a format tool, if can lsp format be applied to lsp?

There is a format tool in progress in https://github.com/slint-ui/slint/tree/master/tools/fmt
We should include it in the LSP.

#2475 I make a pull request, I make format to a crate, it can be used both in format tool and lsp
