[compiler] Add JSX inlining optimization (#30867)

This adds an `InlineJsxTransform` optimization pass, toggled by the `enableInlineJsxTransform` flag. When enabled, JSX will be transformed into React Element object literals, preventing runtime overhead during element creation. TODO: - [ ] Add conditionals to make transform PROD-only - [ ] Make the React element symbol configurable so this works with runtimes that support `react.element` or `react.transitional.element` - [ ] Look into additional optimization to pass props spread through directly if none of the properties are mutated DiffTrain build for [5dcb009](5dcb009)
