[DRAFT, EPIC] Full lambda support

[gstvg]

Some features haven't been implemented and others pulled out from #18921 #21679 to keep it from getting too large (>4k LOC) and should be implemented in follow on PR's:

Major features:

• [DRAFT] Add support for lambda column capture #21323
• [DRAFT] Add lambda substrait support #21193
• Protobuf support
• Making logical LambdaVariable field optional to make it easier for expr_api users
• add HigherOrderUDF to the public user guide docs
• array_transform index parameter

Minor features:

• Named parameters like ScalarUDF already supports: func(a => 3)
• Expr simplifier optimizations for LambdaVariable
• AliasedHigherOrderUDF to add more aliases to an existing HigherOrderUDF
• ListView and Map support in remove_list_null_values and HigherOrderUDF::clean_null_values
• Optional ScalarUDFImpl methods not present on HigherOrderUDF(some are unlikely to be used and could be added on demand only):
  • simplify
  • with_updated_config
  • preimage
  • placement
  • evaluate_bounds
  • propagate_constraints
  • output_ordering
  • preserves_lex_ordering

@gstvg I think we should also include as a folloup adding HigherOrderUDF to the public user guide docs https://datafusion.apache.org/library-user-guide/functions/adding-udfs.html
