Upgrade uses of configgrpc/confighttp (#44591)

#### Description

Follow up to
open-telemetry/opentelemetry-collector#14190,
which introduced an API breaking change: instead of passing a `host
component.Host` to `configgrpc` and `confighttp`'s `ToClient` /
`ToServer` methods, components should instead pass the result of
`host.GetComponents()`. Tests that don't make use of authentication or
middleware extensions, as well as custom component hosts which don't
support extensions (such as the OpAMP supervisor), can simply pass nil
instead of using a no-op host.

Replacing `host` by `host.GetComponents()` is fairly straightforward, as
long as you don't pass in a `nil` host, which unfortunately a lot of
tests do, so I had to fix that as well.

This will be merged into the update-otel PR at #44581.
