[PR] [python] Pass Mosaic options to writer [paimon]
QuakeWang opened a new pull request, #8400:
URL: https://github.com/apache/paimon/pull/8400
### Purpose
Python Mosaic writes built data files with `mosaic.write_table(data, stream)` and did not pass table options into Mosaic `WriterOptions`. As a result, Python tables using `file.format=mosaic` ignored configured `mosaic.num-buckets`, `mosaic.stats-columns`, `file.block-size`, and `file.compression.zstd-level`.
This PR maps the relevant table options into Mosaic writer options and passes them through Python data writers and FileIO implementations.
### Tests
- `python -m pytest pypaimon/tests/mosaic_writer_options_test.py -q`
- `python -m pytest pypaimon/tests/test_format_mosaic_reader_writer.py pypaimon/tests/mosaic_writer_options_test.py -q`
