Previously, the "Compiling <entryPoint>" log message was printed before starting to analyze and transform files, but after creating the `EntryPointBundle` (which includes creating the TS program). Since creating the `EntryPointBundle` involves some work, it is more accurate to move the log message before creating the bundle. PR Close #36626
