[Breaking change] Use suspendable function instead of `Flow` in `GooglePayRepository`

[samer-stripe]

Summary

Replaces the usage of Flow with a suspendable function that returns the result.

Motivation

All consumers of isReady from GooglePayRepository use the returned Flow as a single emitting source by consuming only the first result using first(). Since we are only expecting a single result every time, it is better to represent isReady as a single result suspendable function.

Testing

• [ ] Added tests
• [ ] Modified tests
• [ ] Manually verified
