Resolve PR Workflow issues for OCB Specific Components

[jj22ee]

Description:

Changes:

• Reduced some of the changes of awscloudwatchlogsexporter between upstream and the fork to ensure unit tests build and pass
  • awscloudwatchlogsexporter is NOT an OCB component
• In PR workflow, disable crosslink (expects that "replace" is present for all modules) as some of the "replace" statements are removed to reduce conflicts as OCB components may depend on different OTel dependency versions
• In otelcontribcol test (builds Collector with all components), remove OCB components as they depend on different OTel dependency versions and can cause conflicts
• Remove "replace" statements for OCB components due to version conflicts

OCB component testing are expected to be tested via a different e2e testing mechanism. The PR workflows are still expected to verify linting and unit tests for OCB components, while they are not used to test building the collector alongside all other components.
