Same "Columns" selector as in the Sylius admin (Sylius/Sylius#19291), for BootstrapAdminUi grids.

• The changes are applied when the dropdown is closed. The visibility is kept in the URL (?visibility[total]=hidden).
• Rendered by the new sylius_admin.common.index.content.grid.data_table#toolbar hook.
• The visible field option is documented in docs/grid/fields.md.
• Tests: TemplatesTest for the rendering, and a node:test file for the Stimulus controller.

BC

• The headers and row macros of @SyliusBootstrapAdminUi/shared/helper/table.html.twig now call grid.isFieldVisible(): the grid passed to them has to be a GridView (or implement this method), with the same definition as the one passed to the macro.
• Requires sylius/grid-bundle with GridView::isFieldVisible() (feat(fields): Allow hiding fields by default and overriding their visibility per request SyliusGridBundle#508).

Draft until the grid bundle change is released: the sylius/grid-bundle constraint has to be bumped then.
