PM-15904

📔 Objective

Implement Credential Exchange import flow.
This is part of PM-14800 to implement the new APIs for Credential Exchange on iOS 18.2. Also a continuation of #1198

This also updates the SDK revision to 02332b257970cde14e48a8708e12e722f4a236d9 so that it includes the Credential Exchange functions of the SDK necessary to import/export credentials.

Environment Support

⚠️ This requires Xcode 16.2. The code has several compiler checks #if compiler(>=6.0.3) to ensure that block of code is only compiled when in the proper version of the compiler/Xcode; this ensures Xcode 16.1 (currently in CI/CD) version to continue compiling the project.

Feature enablement

⚠️ In order to enabled Credential Exchange alpha_update_cxp_infoplist.sh needs to be run first to update the Info.plist files with the proper configuration. I've also added this on select_variant.sh with a compiler flag SUPPORTS_CXP so we can trigger builds with this enabled from the CI/CD passing such flag.

Make sure you have OS Settings -> Developer -> Credential Exchange enabled and (in simulator) also a Face ID enrolled and enabled.

Additionally, particularly for the import flow there is a feature flag called cxp-import-mobile that also needs to be enabled. Otherwise, the import flow will show an error when the Bitwarden app opens. If on DEBUG mode, you can also change it in the DEBUG view while seeing the error and retry the operation.
