atmos list should be able to filter for real and abstract components

### Describe the Feature

since atmos version 1.110 `atmos list' is implented instead of a custom command.

This is a good thing, as it is much faster then using the custom command.

But It can no longer be overwritten using atmos.yaml custom command. For me it now lacks the functionality to filter for real or abstract components.

### Expected Behavior

add functionality to filter for real / abstract components

### Use Case

if you have a lot of abstract components, filtering is important

### Describe Ideal Solution

add flag --type / -t to filter for abstract / real components

### Alternatives Considered

_No response_

### Additional Context

_No response_

Start at the `atmos list` CLI entry point and inspect how it currently selects components. Add the requested `--type`/`-t` filtering for real and abstract components, then verify that each option limits the listed components as expected.
