`apple_framework` copies `.swiftmodule` files into app bundle when used with dynamic `vendored_xcframeworks`

Hi,

apple_framework copies .swiftmodule files into app bundle when used with dynamic vendored_xcframeworks.

This seems to be unnecessary.

This can be validate by running the following commands on latest master

$ bazelisk build //tests/ios/xcframeworks/Basic:XCFrameworksApp --apple_platform_type=ios
...
INFO: Build completed successfully, 1 total action
$ cp bazel-bin/tests/ios/xcframeworks/Basic/XCFrameworksApp.ipa XCFrameworksApp.zip
$ unzip -qq XCFrameworksApp.zip
find Payload/XCFrameworksApp.app -name '*.swiftmodule'
Payload/XCFrameworksApp.app/Frameworks/BasicXCFrameworkDynamic.framework/Modules/BasicXCFrameworkDynamic.swiftmodule

Furthermore when building with xcodebuild, .swiftmodule are never copied into app bundle.

This can be validate by building the following example project.

Just for reference, I was hoping that maybe apple_dynamic_xcframework_import doesn't have this issue, but it's the same:

bazelbuild/rules_apple#2510
