Xcode: Fix XCODE_EMBED_FRAMEWORKS when settings differ across targets In commit 5651901c54 (Xcode: add support for embedding frameworks, 2020-10-24, v3.20.0-rc1~402^2) we incorrectly reused `PBXBuildFile` instances when the same framework is embedded in multiple targets, causing target-specific settings to conflict. Fixes: #26438
