Improve dependency tracking in XC models

[lacasseio]

Inspect will show more information about target dependencies. We are tracking explicit, implicit via build phase files and Swift PM dependencies. Here is an example for the Wikipedia target:

name: Wikipedia
dependencies:
 - :Wikipedia@WMF (implicit dependency via file '$(BUILT_PRODUCT_DIR)/WMF.framework' in build phase 'Link Binary')
 - product 'Components' (implicit dependency via package at 'https://github.com/wikimedia/wikipedia-ios-components.git' which require branch 'main' in build phase 'Link Binary')
 - :Wikipedia@WidgetsExtension (implicit dependency via file '$(BUILT_PRODUCT_DIR)/WidgetsExtension.appex' in build phase 'Embed Foundation Extensions')
 - :Wikipedia@NotificationServiceExtension (implicit dependency via file '$(BUILT_PRODUCT_DIR)/NotificationServiceExtension.appex' in build phase 'Embed Foundation Extensions')
 - :Wikipedia@ContinueReadingWidget (implicit dependency via file '$(BUILT_PRODUCT_DIR)/ContinueReadingWidget.appex' in build phase 'Embed Foundation Extensions')
 - :Wikipedia@Wikipedia Stickers (implicit dependency via file '$(BUILT_PRODUCT_DIR)/Wikipedia Stickers.appex' in build phase 'Embed Foundation Extensions')
 - :Wikipedia@WMF (implicit dependency via file '$(BUILT_PRODUCT_DIR)/WMF.framework' in build phase 'Embed Frameworks')
 - :Wikipedia@WMF (explicit)
 - :Wikipedia@ContinueReadingWidget (explicit)
 - :Wikipedia@Wikipedia Stickers (explicit)
 - :Wikipedia@WidgetsExtension (explicit)
 - :Wikipedia@NotificationServiceExtension (explicit)
