Issue Description

378 Set all queries to the macOS Keychain to kSecUseDataProtectionKeychain == true by default. Though this is recommended by Apple to make the macOS and iOS Keychains behave the same way, it causes the issue of preventing saved items to the Keychain from being queried in Swift Playgrounds and other macOS environments (SPM XCTest) that do not have the ability to configure the Keychain.

Related issue: #n/a

Approach

For macOS, default to not setting kSecUseDataProtectionKeychain == true and provide the usingDataProtectionKeychain option when configuring the SDK. Developers can decide to set usingDataProtectionKeychain == true which will cause all macOS queries to use kSecUseDataProtectionKeychain == true and make the macOS Keychain behave like the iOS Keychain.
