Add the switch running OptProf tasks

[GangWang01]

In the case there isn't available VS manifest files from VSDrop, internal build is blocked by OptProf tasks. This needs another mode that opts out of all OptProf tasks. Then add the switch running OptProf tasks or not.

Pull Request Overview

Adds a new toggle to conditionally run or skip all OptProf tasks in the .vsts-dotnet pipeline.

• Introduce EnableOptProf boolean parameter (default: true) to opt out of OptProf tasks when needed.
• Update each OptProf-related task’s condition to include EnableOptProf.

• [nitpick] Consider adding a brief comment above this parameter to explain its effect on the pipeline (e.g., which tasks are skipped when disabled) to improve clarity for consumers of the YAML.

- name: EnableOptProf

.vsts-dotnet.yml:160

• [nitpick] Since this conditional is repeated for multiple tasks, you could extract and(succeeded(), ${{ parameters.EnableOptProf }}) into a reusable template expression or variable to reduce duplication and simplify future updates.

          condition: and(succeeded(), ${{ parameters.EnableOptProf }})
