invoices: add invoice htlc interceptor service
This commit introduces a new invoice htlc interceptor service
that intercepts invoice HTLCs during their settlement phase. It forwards
HTLCs to a subscribed client to determine their settlement outcomes.

This commit also introduces an interface to facilitate integrating the
interceptor with other packages.
