[Enhancement] - Add support to freeze/unfreeze columns in data-table

[ItsKDaniel]

Description of the enhancement: Add support in the data-table settings to freeze and unfreeze columns on demand, similar to google sheets or Excel.

Use cases:

• freeze rowActions on a data-table with 20+ columns
• freeze first three columns, make the rest scrollable.
• freeze both first three columns and row actions. Make the middle section scrollable.

If this cannot be implemented for the core fw-data-table component, please plan on bringing this to fw-platform-table in the custom objects library.
