fix: Push Provisioning issues on iOS due to Apple bugs

[charliecruzan-stripe]

Summary

There is some unexpected behavior from Apple we need to account for.

1. Calling canAddPasses on any iPad will return false, even though the device can add payment passes, so we removed reliance on that method.
2. There is a bug in iOS which results in the false response from canAddSecureElementPass when a paired Watch is still available for provisioning, so we removed reliance on that method.

Motivation

Temporarily fix push provisioning flow on iPads and when there is a paired watch, until Apple fixes this in PassKit.
