Compiler playground now runs the entire program through `babel-plugin-react-compiler` instead of a custom pipeline which previously duplicated function inference logic from `Program.ts`. In addition, the playground output reflects the tranformed file (instead of a "virtual file" of manually concatenated functions). This helps with the following: - Reduce potential discrepencies between playground and babel plugin behavior. See attached fixture output for an example where we previously diverged. - Let playground users see compiler-inserted imports (e.g. `_c` or `useFire`) This also helps us repurpose playground into a more general tool for compiler-users instead of just for compiler engineers. - imports and other functions are preserved. We differentiate between imports and globals in many cases (e.g. `inferEffectDeps`), so it may be misleading to omit imports in printed output - playground now shows other program-changing behavior like position of outlined functions and hoisted declarations - emitted compiled functions do not need synthetic names --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

Avoid mutable logging enabled state and writing to `process.stdout` within our babel transform.
