[w3c/payment-handler] Remove PaymentInstruments API (PR #408)

PaymentInstruments is the Web API that backs non-JIT install of payment apps (see https://w3c.github.io/payment-handler/). It was designed with the assumption that the browser would store the actual payment instrument details, which has not turned out to be true, and has some privacy leaks. It also has not shipped on any other browser, not have we seen any interest from other browser vendors.

This patch removes the ability to register a payment handler via `paymentManager.instruments` API. Only just-in-time installation is supported from now on.
