WordPressKit as a binary framework

[kean]

Changes

• Install WordPressKit using SwiftPM and remove the code from the repo
• Remove wpxmlrpc dependency from the app
• Remove NSObject-SafeExpectations dependency from WordPressAuthentificator

WordPressKit can now be used as a dependency for any of the internal packages we introduce. WordPressAuthentificator now also has a path to becoming a SwiftPM module.

It also slightly reduces the build time: 103 sec → 94 sec (-9 sec or nearly 9%). It is a bit hard to measure accurately, so take it with a grain of salt.

Remainig steps:

The app already runs, but just to be safe, we need to ensure that the Objective-C dependencies that are currently linked statically in WordPressKit do not create any ambiguity in the Objective-C runtime. I achieved that with WordPressShared by inlining its sources in WordPressKit and prefixing the Objective-C methods with wpkit_.

• Remove wpxmlrpc usages from the app to make sure there is no runtime ambiguous – I already done it before in Remove direct wpxmlrpc usages from the app #23389

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 unit tests for my changes.
• 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.

Testing checklist:

• WordPress.com sites and self-hosted Jetpack sites.
• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• VoiceOver.
• Languages with large words or with letters/accents not frequently used in English.
• Right-to-left languages. (Even if translation isn’t complete, formatting should still respect the right-to-left layout)
• iPhone and iPad.
• Multi-tasking: Split view and Slide over. (iPad)
