Describe the feature that you would like added

our repo uses nodeJS 14 which LTS ends by the end of April 30th.

We need to migrate to NodeJS 16.

Our monorepo contains test leaks/memory leaks which make this migration rather complicated, thus first we need to fix following:

• test leaks in v8 packages
  • test(fluentui/react): fix initial global leaks that were causing OOM issues #27661
• test leaks in v0 packages
  • chore(v0): enable emit only dts and use new conformance test API to narrow down TS Program #27686
• lower memory/cpu consumtions of jest tests
  • test: use isolatedModules for all ts-jest configs to lower memory footprint on CI #27670
• react-conformance OOM issues
  • feat(react-conformance): add new TS config api to be able to specify configName and configDir #27664
  • feat(tools): add conformance setup migration to migrate-converged-pkg generator #27668
  • test: migrate all v9 libraries to use new conformance setup which improves test execution by approx 46% #27669

NOTE:

Those issues have been resolved in my experimental branch as part of CI/Tooling perf evaluation #27359
