Don't run embedBytes() if embedByteArray() is also running. (#1871)

* Don't run `embedBytes()` if `embedByteArray()` is also running.

Both functions insert a constructor, and one class can't have two constructors, much less call `super()` with two different signatures.

I can only assume a bug in Haxe that prevented this from being an issue until now, and that Haxe 5 is fixing the bug.

* Check for `@:autoBuild` only after checking for embed data.

If we ever decide to handle the case of the embed functions being called for non-classes (meaning `getLocalClass()` would return null), we'd handle it in `embedData()`. Therefore `embedData()` should happen first.
