Include platform only integrations in the manifest list api

[bdraco]

Proposed change

This should solve the bug reports that are missing some integrations
which make them ridiculously hard to track down.

Integrations that are platform only are missing from
the /config/info page. A frontend change is needed to address this,
and a core change (this change) is needed to provide the manifest data.

Include integrations that are platform only in the manifest list api

Ensure legacy device trackers get add to hass.config.components as
they were previously all called device_tracker.legacy. ex
device_tracker.ping is now in the list.

frontend: home-assistant/frontend#8698

Hey there @home-assistant/core, mind taking a look at this pull request as its been labeled with an integration (websocket_api) you are listed as a codeowner for? Thanks!

air_quality is missing and notify too even though it isn't an entity component.

It's a bit annoying that we need to remember to extend this list when we add a new base entity integration. Could we extend the manifest for this purpose? @balloob?

Good catch. Will add them.

Looks good!

My comment about extracting the base integration list to the manifests can be a follow up if we think it's worthwhile.
