Mingyu Chen 40be6a0b05 [fix](hive) do not split compress data file and support lz4/snappy block codec (#23245)
1. do not split compress data file
Some data file in hive is compressed with gzip, deflate, etc.
These kinds of file can not be splitted.

2. Support lz4 block codec
for hive scan node, use lz4 block codec instead of lz4 frame codec

4. Support snappy block codec
For hadoop snappy

5. Optimize the `count(*)` query of csv file
For query like `select count(*) from tbl`, only need to split the line, no need to split the column.

Need to pick to branch-2.0 after this PR: #22304
