enhance: support null in c data_datacodec and load null value (#32183)
1. support read and write null in segcore
    will store valid_data(use uint8_t type to save memory) in fieldData.
2. support load null
binlog reader read and write data into column(sealed segment),
insertRecord(growing segment). In sealed segment, store valid_data
directly. In growing segment, considering prior implementation and easy
code reading, it covert uint8_t to fbvector<bool>, which may optimize in
future.
3.  retrieve valid_data.
    parse valid_data in search/query.
