refactor: make BitcoinCheckoutModelExtension support other payment handlers (#6311)

Browse Source 
* refactor: make `BitcoinCheckoutModelExtension` support other payment handlers

The bitcoin checkout extension doesn't have to be tied to the native
bitcoin handler since it only really needs the payment details to be in
a specific format, which can be provided by other handlers aswell,
allowing for better code reuse.

* refactor: initialize payment methods in constructor
