Added support for dotted key paths in Data table column

Summary:
This adds support for the key of DataTableColumn to be a dotted path into a nested object, e.g foo.bar. Currently the typescript types only allow a top level key to be set, making this feature currently unusuable from plugin code.

While this could be addressed in a future commit the intention of this is to allow the user to add custom fields into their table columns at run time

Note there is a side effect to free text search from this commit. Previously it would search all top keys in the object. Now it will only search in columns that are in the table.

changelog: Searching data table will now only search columns in the table, rather than all top level attributes of the object
