TestWTF.WTF_Packed.PackedAlignedPtr

This API test is constantly failing on iOS 16.

HISTORY:

https://results.webkit.org/?suite=api-tests&test=TestWTF.WTF_Packed.PackedAlignedPtr

STDIO:

TestWTF.WTF_Packed.PackedAlignedPtr
        
        /Volumes/Data/worker/Apple-iOS-16-Simulator-Release-Build/build/Tools/TestWebKitAPI/Tests/WTF/Packed.cpp:100
        Expected equality of these values:
          sizeof(key)
            Which is: 6
          4U
            Which is: 4

I was able to reproduce this bug on iOS Debug ToT running the test as follows:

run-api-tests --ios-simulator TestWTF.WTF_Packed.PackedAlignedPtr

I was able to bisect a regression point. This test reproduced at 265930@main, but it did not reproduce at 265928@main. Changes at 265929@main would not have impacted this issue, so it appears that 265930@main is what caused the failure.
