Revert "A sizes attribute parser" (https://codereview.chromium.org/224733011)

Reason for revert:
[blink gardening]
SystemMemoryApiTest.Memory started to fail.

http://build.chromium.org/p/chromium.webkit/builders/Linux%20Tests/builds/35970

I manually bisected in range 171674: 171705.
After r171701, SystemMemoryApiTest.Memory started to fail.

I suspect this patch might be also the cause of the failures of other tests,
such as Storage, StorageAttachment and so on.

Let me revert this.
