feat(Android, Tabs): Update approach for loading external sources for tab icons

[t0maboro]

Description

In the initial approach, we used Coil image loading library. However, after the 1st release, Coil has introduced several issues that had an impact on the stability and maintainability.

After reevaluating other options, we've decided to try migrating to Fresco. This choice aligns better because React Native also relies on Fresco internally. Using Fresco should improve consistency with the RN and reduce our maintenance overhead.

One known limitation is that Fresco doesn't support loading images in SVG format. We’ll need to explore alternative strategies to adapt.

Note:

Slightly depends on: #3214

Fresco doesn't support SVGs, so we decided to handle them by passing assets via the AndroidStudio as vector icons - this approach simplifies a lot of things, especially that

PlatformIconAndroid =
  | {
      type: 'drawableResourceAndroid';
      name: string;
    }

will cover SVGs, so we can omit adding a support here. I'll ensure to mention there that SVG should be passed with drawableResourceAndroid only.

Changes

• Removed Coil
• Replaced logic for Coil ImageLoader with Fresco APIs
• Extracted ImageLoader to a separate file

Test code and steps to reproduce

Tested with BottomTabs example.

Checklist

• Included code example that can be used to test this change
• Ensured that CI passes

I haven't checked the runtime but it looks good!

[kkafar]

Code changes look good. Have a couple of questions / suggestions. Please answer them.

I'll test the runtime in a moment.

Let's just make it internal and we're looking good.

I'll test runtime in a moment & if everything is fine, we can proceed.

Hey! Started to test the runtime & noticed that our TestBottomTabs require update!

Can we create dedicated test / example screen (maybe that's even better) that tests images with bottom tabs?

Edit: was checked out on wrong PR, sorry for confusion

[kkafar]

Tested the runtime -- seems to work fine. Great job here.

Note

There is one thing I still don't like - and it is that we have a icon loading logic inside component view manager. I don't think this should block this PR from landing, however we should create a ticket for a small refactor (and first discussion about how it should be organised). Would you do it?
