Add support for proper positional info in swc tree

*   Fix some positional info in SWC error messages
*   Add positional info in `to_document` on duplicate layouts
*   Add support for `path` on `Program` (`to_swc`, `to_document`, `jsx_rewrite`),
    for the path of a file on disk
*   Add support for `development` to `jsx-rewrite`, which when defined will embed
    info on where tags were written into the runtime code when they are not passed
*   Refactor to move some utilities to `micromark_swc_utils.rs`, `swc_utils.rs`
