### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: FileScannerV2 did not support Doris Native files. This
change adds a native v2 FileReader implementation instead of wrapping the
legacy NativeReader. The reader validates the Native header, reads serialized
PBlock payloads, caches and replays the first block for schema probing, exposes
nullable file-local schema, projects requested columns, and applies file-local
filters. Shared materialized-column filtering is also used by JSON and
delimited text readers so predicate accounting stays consistent. WAL is
intentionally not implemented on the v2 path because current group commit WAL
scans are load scans and FileScanOperator only selects FileScannerV2 when
src_tuple_id does not resolve to an input tuple.
### Release note
None
### Check List (For Author)
- Test:

- Unit Test: not run locally because sandbox execution cannot write
.git/modules for submodule setup and cannot download datasketches-cpp; the
attempted run-be-ut command failed before compiling tests.
- Behavior changed: No
- Does this need documentation: No
