Refactoring the ParquetTools read/write APIs

[malhotrashivam]

1. Marked a number of parquet read/write APIs as @deprecated. These include methods that accept java File objects, and will be replaced by methods accepting String instead.
2. Added a few new ParquetInstruction to replace some APIs:
   • Methods which accept a TableDefinition have been deprecated and will be replaced by setting a new instruction for the definition.
   • Similarly, a new instruction for Parquet file layout has been added, which will replace APIs inside ParquetTools which had layout names in the method name (Ex. readSingleFileTable will be replaced by readTable with layout set as single file).
   • Added a new instruction for providing index columns for writing. This will be the new default approach and older APIs have been deleted since those were not released yet.
3. Moved some public utility methods outside of ParquetTools, to prevent internal methods being exposed as APIs.
4. In the python code, deprecated an argument col_definitions in favor of table_definition in parquet reading and writing APIs.

Initial work for this change was started as part of #5206, and has now been moved over to this PR.

Spitballing a bit, I wonder how much better can get these APIs with bifurcated read and write instructions.
Do we really need table[], destination[]? I imagine a PartitionedTableFactory.of(Table[]) could give us the Tables, but flat layout doesn't have a naming scheme right now.
