[component] Add namespace parameter to component.BuildInfo

[dpaasman00]

Description

Adds a new field to component.BuildInfo to facilitate support for reporting the service.namespace semantic convention in OpAMP. Includes corresponding updates to resource attributes reported by the collector. Also adds a new parameter to the builder configuration to facilitate setting this via the OCB.

Link to tracking issue

Fixes #12505

Need follow up PR to OpAMP extension making use of this value.

Testing

Relevant unit tests updated.

Running the updated otelcorecol with logging enabled in service.telemetry and the new resource attribute for service.namespace shows up. This was done sending to another collector running the otlp receiver and logging via the debug exporter.
