Subject: [PATCH 01/40] Introduce component status reporting

This is an alternate to https://github.com/open-telemetry/opentelemetry-collector/pull/6550

- Add component status concept. Components can report their status via
  Host.ReportComponentStatus(). Interested extensions can watch status events
  if they implement StatusWatcher interface.
  This is similar to how PipelineWatcher works today.
- Deprecate Host.ReportFatalError() in favour of Host.ReportComponentStatus().

- healthcheck extension must implement StatusWatcher.
- Replace all ReportFatalError() calls by ReportComponentStatus() calls in core and contrib.

- StatusWatchers need to be able to tell if all current components are healthy.
  It is assumed that the listeners need to maintain a map of components and track
  the status of each component. This works only if we assume that the set of
  components cannot change during the lifetime of the listener. This assumption
  is true today but can change in the future if we introduce partial pipeline
  restarts where only modified/added/removed components are recreated (this will
  break listener's assumption and the map will become invalid). Should we
  instead keep track of this entire status map in the Host and broadcast the
  entire status to the listeners as a whole instead of (or in addition to)
  individual component events?

Subject: [PATCH 02/40] Get things working after rebase

This picks up where https://github.com/open-telemetry/opentelemetry-collector/pull/6560
left off. The first step is to get the code introduced in that PR working with the collector
as it is today. There were significant changes to how pipelines are built and the
component package was split into separate packages based on type (extension, processor, etc).
This commit makes the necessary changes to get everything working, likely not in the most
ideal way, but it's a start that we can iterate on.

Subject: [PATCH 37/40] Fix automatic status reporting for SharedComponents

Automatic status reporting for a SharedComponent needs to go through
its telemtry settings in order to keep status reporting for the component
and its instances in sync. This overrides the automatic status reporting
that occurs in graph, and makes the reporting in graph essentially a no-op
as the SharedComponent premptively transitions state during start and
shutdown.
