[vm/ffi] Roll package:ffi to 1.0.0

G3 has been migrated (go/dart-ffi-1.0-g3-migration), so now we can roll
the package version which has all the deprecated methods removed.

Rolling `package:ffi` forward also means it is no longer using
`sizeOf<T>()` generically. So the problems in the CFE expect files
disappear.
