Protos does not collect data.

Required reason APIs searched for using:
```

`./third_party/utf8_range/...` - tool for utf that is not in user binaries
`./src/google/protobuf/map.h` - resolved with pull#15554
`./src/google/protobuf/io/io_win32.cc` - windows code
`./src/google/protobuf/testing/file.cc` - testing code not in user binaries
`./src/google/protobuf/compiler/importer.cc` - compiler code not in user binaries

So no required reason APIs.

Apple has not yet communicated how this is to be put into podspecs so saving for future commit.

Closes #15557

There are no restrict calls, so the manifest asserts that.

The CocoaPods support now ensure you are using CocoaPods >= 1.12 as that
avoids all the know bugs in CocoaPods support needed to capture the
Privacy Manifest in a resource bundle.

CocoaPods fails spec validation for some warnings, so use a local
to avoid warnings for 64->32bit implicit conversions. This comes up
for watchOS builds.
