com.bumptech.glide.load.engine.GlideException: Failed to load resource EOM

**Glide Version**: 4.16.0

**Integration libraries**: none

**Device/Android Version**: API 30 emulator

**Issue details / Repro steps / Use case background**:
I'm trying to migrate by complex SVG loading setup from v3 to v4. I had a `.decoder(new SvgDecoder())` in v3.

Now I have:
```java
registry.prepend(InputStream.class, SVG.class, new SvgDecoder());
registry.prepend(SVG.class, Bitmap.class, new SvgBitmapDecoder());
```
which I know is wrong now, but that's more the reason to have good error handling for this case!

**Glide load line / `GlideModule` (if any) / list Adapter code (if any)**:
```java
FutureTarget target = Glide
.with(context)
.asBitmap()
.decode(SVG.class)
.diskCacheStrategy(DiskCacheStrategy.NONE)
.load(svgRes)
.submit(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)
```

**Stack trace / LogCat**:
```ruby
class com.bumptech.glide.load.engine.GlideException: Failed to load resource

```

The problem is that `GlideException` is created with a list of 0 causes:
which in turn when calling `logRootCauses` prints nothing.

---

At the very least there should be a warning printed that there are no causes!
But a better solution is to explain why by providing a "fake" cause from `notifyFailed()` detailing why there were no causes even though the decode failed.
