[Feature Request]: Allow adding submenus in TableRowAction

Feature Request Description

Currently ui5-table-row-action only supports single level menu on overflow. It would be nice to have a native option for adding submenus in table actions menu.

Proposed Solution

Allow nesting ui5-table-row-action in the same way as ui5-menu-item in this example to create multi-level menus. For instance, the snippet for "Open" action would be something like

<ui5-table-row-action slot="actions" text="Open" icon="open-folder">
    <ui5-table-row-action text="Open Locally" icon="open-folder">
        <ui5-table-row-action text="Open from C"></ui5-table-row-action>
        <ui5-table-row-action text="Open from D"></ui5-table-row-action>
        <ui5-table-row-action text="Open from E"></ui5-table-row-action>
    </ui5-table-row-action>
    <ui5-table-row-action text="Open from Cloud"></ui5-table-row-action>
</ui5-table-row-action>

Depending on how the first level action is displayed, the behaviour could be as follows:

• If action is displayed in overflow menu, then it should have a submenu arrow icon, and a second level submenu appears on hover. Exactly the same behaviour as ui5-menu-item, basically.
• If action is not moved to overflow menu and simply displayed as a button in the table, then clicking the button opens the second level submenu.

Proposed Alternatives

1. Using ui5-menu and ui5-button directly to replicate ui5-table-row-action functionality
2. Creating second level submenus separately and opening them on mouseenter or click
3. Monkey patching ui5-table-row-action
4. Give up on the submenus idea and have one single-level menu with lots of options.

Start by comparing the requested nesting behavior with ui5-menu-item and the linked playground example, then inspect the ui5-table-row-action component entry point. Verify both overflow-menu submenus and inline button behavior, including the proposed nested markup, before considering the feature complete.
