#34778#34849
fix two problems:
1. count(*) incorrect, if growing insert duplicated (pk, timestamp)
pairs that pk and timestamp all same, need to keep just one pair.
2. count(*) may core dump, if get_real_count interface get snapshot and
do mvcc at not consistency status, mainly happens under concurrency.

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.

This PR adds the ability to search/get sparse float vectors in segcore,
and added unit tests by modifying lots of existing tests into
parameterized ones.
