[configgrpc] Mark module as 1.x (#15609)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description

Marks `configgrpc` module as 1.0.

Removes dependency on `otelcol`.

Items for marking this as stable:
- The only item on the tracking configgrpc issue was #12836, after
looking into it I think it can be removed from the tracking issue since
the breaking part was done already on #14267.
- On my mind there was also the `otelgrpc` dependency. There are two
things that make me think this is fine now:
1. RPC metrics emitted now by the `otelgrpc` dep are 'release candidate'
stability so the chance of breakage is very low; there have been [no
relevant
changes](https://github.com/open-telemetry/semantic-conventions/commits/v1.43.0/docs/rpc/rpc-metrics.md?since=2026-02-19&until=2026-07-20)
since February
2. Our documentation makes it clear that these are not covered by
stability guarantees
https://opentelemetry.io/docs/collector/internal-telemetry/#ownership-of-emitted-metrics
- There are a few PRs by @evan-bradley that we should merge before we
land this
    - #15615
    - #15616
    - #15611
    - #15610
 
<!-- Issue number if applicable -->
