Implement apple_archive rule to stop generating .ipa and .zip files from {platform}_application targets

[adincebic]

We want to decouple creation of .ipa and .zip files from {platform}_application rules. This implies enabling tree artifacts for those application rules by default.

• Implemented new apple_archive rule for packaging Apple bundles into .ipa files
• Made sure to preserve existing functionality for packaging Symbols, Swift support files and so on.
• Created new providers (AppleSymbolsFileInfo, AppleSwiftDylibsInfo, AppleWatchosStubInfo, AppleMessagesStubInfo) for propagating archive-specific metadata
• Enabled tree artifact outputs by default for iOS/tvOS/visionOS applications to support .ipa creation
• Removed include_symbols_in_bundle attribute from ios_application (symbols now handled separately via apple_archive)
• Updated tests to reference newly created apple_archive targets which now exercise this rule.
• Updated documentation

Remaining things to do:

• Rename all occurrences of ipa_post_processor to post_processor
• Support producing .zip archives for macos_application. This is a little tricky since there is framework rules that don't support tree artifacts for macOS.
• Remove all tree artifacts related code from processor.bzl
