Skip applying scale by local relaunch item

If a scaled app calls Activity#recreate(), it will perform
a local relaunch from ActivityThread#handleRelaunchActivityLocally.
That uses the current config to execute, which was already scaled.
So to avoid double scaling, do not apply the scale if the
transaction item is executing from local.

Fix: 264133971
Test: atest ActivityThreadTest#testOverrideScale
