[feature]: Show custom channel data in lncli closedchannels

[Liongrass]

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

I would like to be able to inspect closed taproot asset channels, like how I inspect closed lightning channels.

Describe the solution you'd like

I would like the command lncli closedchannels to returm custom channel data in the same way that lncli listchannels does

Describe alternatives you've considered

Additional context

[Liongrass]

Ideally the custom channel data could be added to lncli pendingchannels as well
