Add amount and label to GooglePayLauncher and GooglePayConfiguration

[tillh-stripe]

Summary

This pull request adds support for providing a custom amount (for setup intents) and a custom label when opening the Google Pay bottom sheet.

For GooglePayLauncher, we add both properties to presentForSetupIntent() and the label property to presentForPaymentIntent().

For GooglePayPaymentMethodLauncher, we add the label property to present(), as the amount property already exists.

For PaymentSheet.GooglePayConfiguration, we add both properties to the constructor. We also remove one redundant constructor.
