feat(es/codegen): Introduce SpanWriter and adjust_span

[kdy1]

Description:

We can expand

#[node_impl]
impl MacroNode for Program {
    fn emit(&mut self, emitter: &mut Macro) {
        match self {
            Program::Module(m) => emit!(m),
            Program::Script(s) => emit!(s),
        }
    }
}

to

impl crate::Node for Macro {
    fn emit_with<W, S>(&self, e: &mut crate::Emitter<'_, W, S>) -> Result
    where
        W: crate::text_writer::WriteJs,
        S: swc_common::SourceMapper + swc_ecma_ast::SourceMapperExt,
    {
        {
            match self {
                Program::Module(m) => Node::emit_with(&m, emitter),
                Program::Script(s) => Node::emit_with(&s, emitter),
            }
        }
    }

    fn adjust_span<W, S>(&mut self, wr: &mut crate::SpanWriter<'_, W, S>) -> Result
    where
        W: crate::text_writer::SpannedWriteJs,
        S: swc_common::SourceMapper + swc_ecma_ast::SourceMapperExt,
    {
        {
            match self {
                Program::Module(m) => Node::adjust_span(&mut m, emitter),
                Program::Script(s) => Node::adjust_span(&mut s, emitter),
            }
        }
    }
}
