WIP: Custom app launcher icons

[thomashorta]

Fixes #14476

Implement custom icons that can be selected by the user both for WordPress and Jetpack. This is still WIP as it will most likely be separated in smaller PRs, and it's also missing some unit tests and UI improvements, and still needs some minor issue fixes.

To test:

Regression Notes

1. Potential unintended areas of impact

2. What I did to test those areas of impact (or what existing automated tests I relied on)

3. What automated tests I added (or what prevented me from doing so)

PR submission checklist:

• [ ] I have completed the Regression Notes.
• [ ] I have considered adding accessibility improvements for my changes.
• [ ] I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Just a heads up this PR will stay in Draft for a bit as there are some things still needed for it to be ready for review and merge.

This is fairly out-of-date – we might need it again in the future but closing for now.
