kernel: Add functions for the block validation state to C header

Browse Source 
These allow for the interpretation of the data in a `BlockChecked`
validation interface callback. The validation state passed through
`BlockChecked` is the source of truth for the validity of a block (the
mode). It is
also useful to get richer information in case a block failed to
validate (the result).
