feat: switch from @linaria/shaker to @griffel/transform-shaker (#795)

* feat(transform): replace @linaria/shaker with @griffel/transform-shaker

Replace the external @linaria/shaker dependency with the internal
@griffel/transform-shaker package. Since the new shaker produces ESM
output (vs Babel-compiled CJS from the old shaker), add an ESM→CJS
converter in Module.evaluate so code can run inside vm.Script's
function wrapper.

Also fix several shaker graph-builder bugs uncovered during integration:
- ImportDeclaration not kept alive when its bindings are referenced
- ExportNamedDeclaration declarators removed from shaken output
- Missing TemplateLiteral:expressions and SpreadElement:argument handlers
- Computed Property:key not treated as a variable reference

* refactor: remove StrictOptions, babelOptions, and simplify Evaluator signature

- Remove StrictOptions type (was just { rules: EvalRule[] })
- Remove babelOptions from TransformOptions and all call sites
- Simplify Evaluator to (filename, text, only) => [string, Map | null]
- Module class now takes rules: EvalRule[] directly
- Remove config-babel-options fixture and test
- Remove private: true from transform-shaker
- Add @griffel/transform-shaker dependency, remove oxc-transform
