[Payment Request] Change the lifetime management of PaymentRequestImpl

Was previously 1 PaymentRequestImpl per WebContents. Now there is a
PaymentRequestWebContentsManager (1 per WebContents) that owns all the
PaymentRequestImpl's, whose raw pointers are shared with the delegate
and the mojo bindings.

Also, moving PaymentRequestImpl from chrome/ to components/ which creates
the need for a PaymentRequestDelegate (initially managing the Chrome
dialog).
