fix(PrivacyInfo) SPM/Cocoapods support for privacy manifest

[sdurban]

Summary

This PR adds exporting of the PrivacyInfo information added in version 8.18.0 for use via SPM and Cocoapods.

I have tested it with SPM and Cocoapods sample projects, and now it successfully fetches the information.

The process to add it in Cocoapods is the same as used by multiple projects. Ref. CocoaPods/CocoaPods#10325 (comment) and to add it in SPM, I have looked at other projects such as Revenuecat https://github.com/RevenueCat/purchases-ios/blob/main/Package.swift.

Hello @wlxo0401 and @sdurban. Unfortunately, these changes do not effectively address the issue.
Using syntax

<spec>.<platform>.resources

produce a copy into the target bundle (as per official documentation) also for static linking process there is strongly recommend to use different way of attaching resources into the pod should be used.

<spec>.<platform>.resource_bundle

so the spec should looks like this.

...
s.ios.resource_bundles = {
    "#{s.module_name}" => 'Sources/Resources/*.{der}'
    "#{s.module_name}_Privacy" => 'Sources/PrivacyInfo.xcprivacy'
  }
...
s.tvos.resource_bundles = {
    "#{s.module_name}" => 'Sources/Resources/*.{der}'
    "#{s.module_name}_Privacy" => 'Sources/PrivacyInfo.xcprivacy'
  }
...
s.osx.resource_bundles = {
    "#{s.module_name}" => 'Sources/Resources/*.{der}'
    "#{s.module_name}_Privacy" => 'Sources/PrivacyInfo.xcprivacy'
  }
....
s.watchos.resource_bundles = {
    "#{s.module_name}" => 'Sources/Resources/*.{der}'
    "#{s.module_name}_Privacy" => 'Sources/PrivacyInfo.xcprivacy'
  }
...

Current Amplitude-iOS version 8.19.1 for cocoapods linked statically produce a compile error

Multiple commands produce .... PrivacyInfo.xcprivacy .... script phase “[CP] Copy Pods Resources”

if i add my own PrivacyInfo.xcprivacy file into the target. What do you think about it?

Hello @astrokin,

You're right. There is a problem with cocoapods definition if you use cocoapods without use_frameworks.

If you use use_frameworks!, the pods are integrated as frameworks rather than static libraries. This means the file belongs to the framework and not to your project, thereby avoiding this issue.

Perhaps it would be best to leave the .der files copied and place the privacy file in its own bundle as you suggested.

I'll submit another PR this week to address this issue, @crleona or you can fix It with a PR @astrokin if you want.
