ppcp-paypal-subscriptions SettingsProvider migration (5611)

[Dinamiko]

This PR replaces wcgateway.settings service with the new SettingsProvider in ppcp-paypal-subscriptions module.

PR Changes

• Adds get_subscriptions_mode() to PayPalSubscriptionsModule, this method is the same as the one created in ppcp-wc-subscriptions module, we'll reuse it from there once merged and delete it from here. The reason to not add it to SettingsProvider is because we'll need to inject new services and we do not want to do that in SettingsProvider.
• Replaces get subscriptions mode in all locations where Settings is used
