[PM-14800] Credential Exchange implementation preparation

PM-14800

📔 Objective

This PR prepares the ground for implementing Credential Exchange flows.
The export and import flows are going to be implemented in separate PRs based on this one. So no export/import operations can be tested so far on this PR.

This is similar to #1138 but mocking the SDK export/import functions so that the app can be properly built with the current SDK version instead of targeting a local SDK version.
When the SDK PR bitwarden/sdk-internal#32 gets merged we need to update the code so it doesn't reference the mocked function anymore.

Environment Support

⚠️ This requires Xcode 16.2 (currently in RC). 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 stable 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. The configuration hasn't been added directly into the Info.plist files so when this is merged to main it doesn't display Bitwarden as an import provider as the work for Credential Exchange is not ready for production.

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

Notes

Info.plist files have some changes regarding reordering the code after plutil commands were done. So that when the new script alpha_update_cxp_infoplist.sh is executed only the specific parts of the code are updated instead of seeing also the rendering.
