Remove Tables.jl as a hard dependency

Tables.jl is now only needed for tests, not as a runtime dependency.
The Tables interface for solution types is provided by RecursiveArrayTools
via its Tables extension (RecursiveArrayToolsTablesExt).

This change:
- Removes Tables from [deps] section (it was never there but listed in compat)
- Removes Tables from [compat] section
- Keeps Tables in [extras] for test dependencies
- Keeps Tables in test target for running tests

The Tables interface continues to work through RecursiveArrayTools extension.
