Enable browser WASM R2R tests in manual pipeline

[lewing]

Summary

Restore the browser WASM CoreCLR R2R_CG2 runtime-test leg removed by #133294, but keep it out of the default runtime pipeline while its failures are investigated.

The leg and its required build jobs are enabled only by runtime-wasm-non-libtests, so it can be queued on a PR with:

/azp run runtime-wasm-non-libtests

Other WASM wrappers and scheduled extra-platform runs retain their existing behavior.

Validation

• Parsed the changed pipeline YAML files successfully.
• Confirmed the changes pass git diff --check.

🔵 Needs a closer look

The “manual pipeline only” intent should be made unambiguous by explicitly disabling PR triggers (e.g., pr: none) in the manual pipeline YAML to avoid accidental automatic execution of the new R2R leg.

Pull request overview

Restores the browser WASM CoreCLR R2R_CG2 runtime-test leg behind an explicit pipeline parameter, enabling it only in the runtime-wasm-non-libtests manual pipeline while keeping default WASM/extra-platform behavior unchanged.

Changes:

• Enable runR2RTests in runtime-wasm-non-libtests to turn on the R2R_CG2 leg for that manual pipeline.
• Add a runR2RTests parameter (default false) to the WASM extra-platforms template and gate the R2R build/test jobs behind it.

File summaries

File	Description
eng/pipelines/runtime-wasm-non-libtests.yml	Enables the R2R leg for this manual WASM non-libtests pipeline by setting runR2RTests: true.
eng/pipelines/extra-platforms/runtime-extra-platforms-wasm.yml	Introduces runR2RTests parameter (default off) and conditionally adds the R2R_CG2 build/run jobs when enabled.

eng/pipelines/runtime-wasm-non-libtests.yml:35

• If the intent is for runtime-wasm-non-libtests to be manual-only (queued via /azp run), this pipeline file currently doesn’t disable PR triggers (there’s trigger: none but no pr: none). With runR2RTests: true added, an accidentally-enabled PR trigger would run the R2R leg automatically on PR updates, which conflicts with the PR description’s “manual pipeline” goal. Consider explicitly adding pr: none near the top of the file to make the behavior unambiguous.

I'm working on the active issues/skips, but being able to verify while doin that would be nice then we can move it back to required once things are green.
