refactor: update static computed properties to static, move to experimental react compiler

[joshblack]

Closes #

This PR updates our React Compiler packages to the current experimental build so the local migration check matches the compiler behavior in the playground more closely.

With the newer compiler, dynamic template-literal object keys compile without the source rewrites we were adding before. As a result, this PR keeps the source changes focused on computed object-pattern destructuring that still fails the compiler check.

Changelog

New

• Add a changeset for the @primer/react React Compiler runtime dependency update.

Changed

• Update babel-plugin-react-compiler across the repo to 0.0.0-experimental-a1856f3-20260507.
• Update react-compiler-runtime in @primer/react and @primer/styled-react to 0.0.0-experimental-a1856f3-20260507.
• Replace computed object-pattern destructuring in the remaining failing files with static property destructuring.
• Remove React Compiler diagnostic filtering from @primer/react-compiler-check so compile errors are surfaced directly.

Removed

• Remove the workaround-style rewrites for dynamic template-literal object keys since the experimental compiler handles those cases.

Rollout strategy

• Patch release
• Minor release
• Major release; if selected, include a written rollout or migration plan
• None; if selected, include a brief description as to why

This should be a patch: it updates internal compiler tooling and the published compiler runtime dependency, without changing the public component API.

Testing & Reviewing

Verified the compiler migration path and focused package checks:

• npm run lint:react-compiler -w @primer/react
• npx vitest run packages/react-compiler-check/src/index.test.ts
• npm run type-check -w @primer/react-compiler-check
• npm run type-check -w @primer/react
• npm run type-check -w @primer/styled-react

Pull request overview

This PR updates the repo’s React Compiler toolchain to a newer experimental build (to better match compiler behavior in the playground) and adjusts a handful of call sites to avoid computed-property destructuring patterns that still fail compiler checks. It also adds a changeset to capture the published @primer/react runtime dependency bump.

Changes:

• Bump babel-plugin-react-compiler across the repo and bump react-compiler-runtime for @primer/react (and devDependency usage in @primer/styled-react) to 0.0.0-experimental-a1856f3-20260507.
• Replace computed-key object destructuring (e.g. {['aria-label']: x}) with static string-literal destructuring (e.g. {'aria-label': x}) in the remaining affected files.
• Add a changeset for the @primer/react runtime dependency update and update the lockfile accordingly.
