Android Table does not scroll horizontally

### Describe the bug

Since the horizontal scrollview has been removed from the Android implementation of Table, it is not possible anymore to make the table scroll horizontally.

I tried to add the Table into a ScrollContainer, but the horizontal scrolling was still not working.

I then put the Table into a Box along with a very long Label. Then, the window did scroll horizontally, but I did not see more of the Table content than before. All the Table content to the right did not move into view.

```
_scroller = toga.ScrollContainer(horizontal=True, vertical=False, style=Pack(flex=1))
_scrolling_box = toga.Box(style=Pack(flex=1, direction=COLUMN))
_scrolling_box.add(toga.Label("fdskjfdksfjdkls fjdks fjdklsfjdkls fjdklsfjdklsfjdsfjklds fjklds jfdkls fjklds fjdsfjfklsd fjs fkdsf dsjf dskl kfsd jdkls fjdsklf jdsklfjsfljlsk"))
self._table = toga.Table(
headings=[
_("app.Table.name"),
_("app.Table.systemApp"),
_("app.Table.version"),
_("app.Table.versionCode"),
_("app.Table.location"),
_("app.Table.packageName"),
],
accessors=["appName", "systemApp", "appVersion", "appVersionCode", "appLocation", "appPackageName"],
missing_value="",
style=Pack(flex=1, font_size=G.config["font_size"]),
)
_scrolling_box.add(self._table)
_scrolling_box.add(toga.Label("fdskjfdksfjdkls fjdks fjdklsfjdkls fjdklsfjdklsfjdsfjklds fjklds jfdkls fjklds fjdsfjfklsd fjs fdks fjkdls jfdkls fjdkls fjdkls fjdkls fjds fj"))
_scroller.content = _scrolling_box
self.main_box.add(_scroller)
```

### Steps to reproduce

1. add a Table to a ScrollContainer with horizontal=True
2. add a lot of colums, so the Table content becomes wider than the screen width
3. try to scroll horizontally

### Expected behavior

It is possbile to scroll the Table content horizontally

### Additional context

_No response_

Start with the Android Table implementation and reproduce the issue using a Table with more columns than the screen inside a horizontal ScrollContainer. Done means the table's off-screen columns can be brought into view horizontally on Android, with the existing reproduction steps passing.
