LSP: Support formatting

[phated]

Problem

The LSP should support formatting files when requested (on save, on code action, etc) following https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_formatting

Happy Case

A user should be able to run the formatting command in their editor running an LSP client and the source code document will be updated with the formatted code.
