Merge bitcoin/bitcoin#24032: Add defaults to vDeployments to avoid uninitialized variables
c4c5b9ca6e98cf44309af73edf5559940a04d00f consensus/params: set default values for BIP9Deployment (Anthony Towns)
Pull request description:
Adds default values for `vDeployments` in `consensus/params.h` so that undefined behaviour is avoided if a deployment is not initialized. Also adds a check in the unit tests to alert if this is happening, since even if it doesn't invoke undefined behaviour it's probably a mistake.
