Revert^2 "Add code size to CodeInfo"

This temporarily adds 0.25% to oat file size.
The space will be reclaimed back in follow-up CL.

This reverts commit 8f20a23a35fa6fbe4dcb4ff70268a24dc7fb2a24.

Reason for revert: Reland as-is after CL/903819

Bug: 123510633
Test: DCHECK compare the two stored code sizes.
