9.0

• #4933 update syntax bf6561bb5d84 syntax changes listed here

• #4934 generate @pure annotations to help esbuild remove more dead code

• #4932 #4931 turn flow syntax checking from a error into warning 103, so it can be turned off as below

@@config({
  flags: ["-w", "-103"],
})

%%raw(`
if (import.meta.hot){
  console.log('es6')
}
`)

The rationale is that flow could be not standard compilant so we need provide a work around, here import.meta is something new in Ecmascript
