Revert "Embed external xcframeworks regardless of linking type (#6217)"

[fortmarek]

This reverts commit 3bebe42.

Short description 📝

Some embedded xcframeworks lead to issues when uploading the app to App Store Connect:

ERROR ITMS-90208: Invalid Bundle. The bundle MyApp.app/Frameworks/BrazeKit.framework does not support the minimum OS Version specified in the Info.plist.
Return status of iTunes Transporter was 1: Asset validation failed - Invalid Bundle. The bundle MyApp.app/Frameworks/BrazeKit.framework does not support the minimum OS Version specified in the Info.plist. - STATE_ERROR.VALIDATION_ERROR.90208

We followed Xcode 15.3 behavior but looks like the behavior is buggy: https://forums.developer.apple.com/forums/thread/705297

This means the privacy report won't be generated for these xcframeworks but we haven't seen Apple rejecting apps over that, yet.

How to test the changes locally 🧐

Generate a project with a binary SPM dependency – it shouldn't be embedded

While using mergeable frameworks, symbols from embedded frameworks that are merged as static frameworks are stripped. However, regular static frameworks will be copied entirely.

It automatically leads to an increased binary size.
