Re-enable DynaRec with PAGE16K and fix iOS app build

- Add back -DPAGE16K=ON for A18 Pro 16KB page optimization
- Re-enable DynaRec compilation with proper iOS compatibility
- Update build message to reflect DynaRec is enabled
- Fix iOS app build with CODE_SIGNING_ALLOWED=NO
- Remove -allowProvisioningUpdates to prevent provisioning errors
- This should enable full Box64 performance while building successfully

Now using the original A18 Pro optimization flags as documented
