Replace `omega` tactic with `lia`
Since Coq 8.12, `omega` is flagged as deprecated and scheduled for removal.
Also replace CompCert's homemade tactics `omegaContradiction`, `xomega`,
and `xomegaContradiction` with `lia` and `extlia`.
Turn back on the deprecation warning for uses of `omega`.
Make the proof of `Ctypes.sizeof_pos` more robust to variations in `lia`.
