kernel: Expose consensus parameters (btck_ConsensusParams)

Browse Source 
Library users currently need to maintain a full context object to perform
context-free block validation. Exposing an opaque `btck_ConsensusParams`
struct allows callers to supply only the required consensus parameters,
resulting in a lighter-weight API and a clearer expression of the actual
validation behavior.
