* Avoid creating tasks for checking integrations platforms
This is a followup to #110743 to avoid creating a task to check
if the integration platform exists. We created tasks because
we needed to await async_get_integrations but since its always
called from EVENT_COMPONENT_LOADED firing, we can use the
async_get_loaded_integration version which does not need
to be awaited. This eliminates one task for every loaded
component
* there is no more race risk
* reduce
* coro or callback
* reduce
* tweak
* race safe
* fix type
* fixes
* use built-in helper to make it smaller
* use built-in helper to make it smaller
* use built-in helper to make it smaller
* add coverage to ensure exceptions are logged
* improve readability a bit
* platforms
* Migrate integration_platform helper to use async_get_integrations
We were fetching integrations inside the gather one
at a time. This is inefficent.
* cleanup

* add task name
* small tweaks
* gather only if we have tasks
