feat: update type definitions

allow boolean schemas
async validation promise resolves with data
properties of custom keyword definition ($data and metaSchema)
custom keyword schema can be any value
keyword schema in error object can be any value
optional propertyName property of error object for all keywords (added when validating schema in propertyNames)
propertyNames keyword error params
