Add `ChannelManager::create_bolt11_invoice`

[jkczyz]

Now that the lightning crate depends on the lightning_invoice crate, the utility functions previously living in the latter can be implemented on ChannelManager. Additionally, the parameters are now moved to a struct in order to remove the increasingly combinatorial blow-up of methods.

The new Bolt11InvoiceParameters is used to determine what values to set in the invoice. Using None for any given parameter results in a reasonable the default or a behavior determined by the ChannelManager as detailed in the documentation.

Fixes #3375
