Replace use of libcore.io.SizeOf with X.BYTES.

X.BYTES is part of the Android API since API level 24. Since its
introduction, the internal API SizeOf.X is obsolete. This CL
topic removes use of the obsolete API so that it can be dropped
in a follow-up CL.

Bug: 123174577
Test: Ran CtsLibcoreTestCases at a follow-up CL.
