Subject: 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`.
