feat(babel): rewrite for web (attempt 2) (#27907)

# Why

- Alternative to #24725 which takes a
less radical approach.
- Instead of reimplementing all the functionality, we'll simply remove
the unused babel transforms from the existing preset.

<!--
Please describe the motivation for this PR, and link to relevant GitHub
issues, forums posts, or feature requests.

# Test Plan

- Hopefully all language tests catch any changes.
- This only applies to web and ssr.
