Closes https://github.com/longbridge/gpui-component/discussions/1707
## Description
This change to improve the `TableDelegate` to have `&mut self` and
`Context<TableState<Self>>` to easy access delegate.
## Break Changes

`context_menu`, `render_loading`, `render_empty`,
`render_last_empty_col` in `TableDelegate` has been changed.
```diff
- fn render_th(&self, col_ix: usize, _: &mut Window, _: &mut App) -> impl IntoElement
+ fn render_th(&mut self, col_ix: usize, _: &mut Window, _: &mut Context<TableState<Self>>) -> impl IntoElement
