Move Tables.jl and IteratorInterfaceExtensions.jl to extension

This change moves the Tables.jl integration functionality to a package extension
to reduce precompilation time by avoiding loading heavy table-related dependencies
when they are not needed.

Changes:
- Move Tables.jl and IteratorInterfaceExtensions.jl from deps to weakdeps
- Create RecursiveArrayToolsTablesExt extension with all table traits
- Remove tabletraits.jl from main module
- Reduce compilation time from ~309ms to ~245ms (~20% improvement)

The Tables interface remains fully functional when Tables.jl is loaded,
but no longer impacts basic RecursiveArrayTools usage.
