37492	GeometryField.to_python() crashes with GDALException on invalid GeoJSON when the widget has no deserialize()	Philip Sørensen		"#29978 made `GeometryField.to_python()` catch `GDALException` from `widget.deserialize()`. However, when the widget has no `deserialize()` method (e.g. `widget=forms.TextInput`, which `test_field_with_text_widget` covers), `to_python()` calls `GEOSGeometry()` directly and only catches `GEOSException`, `ValueError` and `TypeError`. For GeoJSON input that GDAL rejects, `GEOSGeometry()` raises `GDALException`, so `clean()` crashes (HTTP 500) instead of raising a `ValidationError`:

```python
from django import forms as django_forms
from django.contrib.gis import forms
forms.GeometryField(widget=django_forms.TextInput).clean(""{}"")
# GDALException: Invalid geometry pointer returned from ""OGR_G_CreateGeometryFromJson"".
```

`'{""type"": ""Foo""}'`, `'{""type"": ""Point""}'` and `'{""type"": ""Point"", ""coordinates"": ""x""}'` crash the same way. This reproduces on 6.1.2, 6.1.3 and main. The default widget isn't affected, because `BaseGeometryWidget.deserialize()` catches `GDALException`.

Patch: add `GDALException` to the exceptions caught in the fallback.
