Performance regression in #33252

[amcasey]

The extra work done in #33252 is valuable, but maybe it doesn't need to be so expensive.

Setup:

1. Clone https://github.com/amcasey/material-ui.git
2. Check out Benchmark
3. yarn to restore packages
4. yarn typescript to prebuild and run some TS tests

Repro

1. tsc -p docs

On a random Mac Mini:

• 10-run avg on 72bb4c2: 30,872ms
• 10-run avg on c5e6d95: 33,268ms (8% slower)

Note: to build old TS commits, you probably need to change const { default: chalk } to const chalk in scripts/build/utils.js.
