Reworked the way we display images in ImageWidgets

[grzesiek2010]

Closes #5430

What has been done to verify that this works as intended?

I've checked the fix manually and added some automated tests.

Why is this the best possible solution? Were any other approaches considered?

It seems to be a bug in Glide bumptech/glide#4035. I've improved the was we display/hide images so that the bug doesn't affect our app. I didn't think of any other solution.

How does this change affect users? Describe intentional changes to behavior and behavior that could have accidentally been affected by code changes. In other words, what are the regression risks?

This may affect any image widget Image/Draw/Annotate/Signature so please test all of them.

Do we need any specific form for testing your changes? If so, please attach one.

The AllWidgets form.

Does this change require updates to documentation? If so, please file an issue here and include the link below.

No.

Done.

As a bonus it makes the show/hide flow for error text clearer. Tests look complete to me.

The "Markup image" button is enabled after adding an invalid image and there is a crash when a user taps the markup button. (Android 10,13)
Steps to reproduce:

1. Go to Annotate widget in All widgets form.
2. Tap "Choose image" button.
3. Add the "broken" file mentioned in the issue.
4. Tap "Markup Image" button.

This is something we also should fix but it throws a different stacktrace so it's not the main issue I wanted to address. Please file a separate issue and we can add it to v2023.2.
