This allows us to remove the table name from the low-level chunk
representations (like `ParquetFile`, RUB, ...) since table names are
already tracked by the higher-level data structures (e.g. catalog,
catalog chunk) that manage the low-level chunk representations.
This is similar to #4167.

Min/max values and distinct counts are already optional, so let's make
the null counts optional as well. This will be helpful for NG to deal w/
partial statistics (e.g. we only populate stats for the time column).
Note that the total count is still mandatory, but we normally have the
chunk/file-level row count at hand.
* refactor: remove InfluxColumnType::IOx
Remove unused column variant - see #3554 for context.
* refactor: reserve SEMANTIC_TYPE_IOX name in proto

This will be helpful when we want to batch DML operations in memory
(e.g. when using RSKafka).
This also ensures that `MBChunk` accounts for the column names that
are stored within `MutableBatch`.
* fix: nocache feature code rot
The MBChunk::snapshot code when using the "nocache" option no longer
compiles - this commit updates it to match the not(nocache) code.
* build: use updated broken_intra_doc_links name
The broken_intra_doc_links lint was renamed
rustdoc::broken_intra_doc_links
https://doc.rust-lang.org/rustdoc/lints.html
* fix: Properly record total_count and null_count in statistics
* fix: fix statistics calculation in mutable_buffer
* refactor: expose null counts in read_buffer
* refactor: expose null_count in parquet_file
* fix: update server crate tests
* fix: update query_tests tests
* docs: tweak comments
* refactor: Use storage_stats rather than adding `null_count`
* refactor: rename test data field for clarity
* fix: fixup merge conflicts
* refactor: rename initial_non_null_count to initial_total_count
* refactor: caculate null_count as row_count - to_add
And use TableSummaryAndTimes with the mutable buffer chunks when turning
them into catalog chunks.
It's proving too big to switch over everything using TableSummary at
once, so this will let us switch over more incrementally.
The entire persistence windows data structures (including the
checkpoints) have nothing to do with the mutable buffer per se. So lets
move them into their own crate. This also makes `parquet_file` not
longer depend on `mutable_buffer`.
