[connector/count] Add support for profiles signal

[mx-psi]

Component(s)

connector/count

Describe the issue you're reporting

This connector would be useful for testing and validation of the experimental profiling signal.

As inspiration for how to add support this PR can be used: open-telemetry/opentelemetry-collector/pull/11071 (there is no connector with support as of the writing of this issue)

Example of configuration using profiles (needs service.profilesSupport feature gate to be enabled):

receivers:
  otlp:
    protocols:
      grpc:
exporters:
  otlp:
    endpoint: ${OTLP_ENDPOINT}
service:
  pipelines:
    profiles:
      receivers: [otlp]
      exporters: [otlp]

I think we need to enhance pkg/ottl to support profile context first, since the countconnector relies on pkg/ottl. 🤔
