[feature]: listchannels output should include node alias

[Roasbeef]

Is your feature request related to a problem? Please describe.

Many applications want to display a node's alias along side the set of displayed channels. Today that information isn't returned, so then an application needs to hit GetNodeInfo for each of the channels, which can really slow down loading 1000s of channels for a large node.

Describe the solution you'd like

Add a new alias field to the ListChannels RPC call.

Describe alternatives you've considered

Applications could use GetNodeInfo with --include_channels, but that'll only show the graph level information and not also the link level information. As an alternatively, we could add more link level channel info here (capacity, balance, etc, etc).

Additionally it would be great to have alias information on the lncli fwdinghistory events, maybe through new fields alias_in and alias_out. Edit: Created a feature request for this: https://github.com/lightningnetwork/lnd/issues/7000

Hi, I have taken up this issue since the related PR is closed since a while. The changes required here resemble changes in https://github.com/lightningnetwork/lnd/pull/7001. I have working code for a peer alias in ListChannels and will submit it with tests soon.
