The current behavior of rosetta (extract) is to use a number of node worker threads equal to half the number of CPU cores. On large CI/CD build hardware, this may mean creating a huge number of worker threads which causes more contention than benefit. Introduce JSII_ROSETTA_MAX_WORKER_COUNT to limit the maximum number of workers (defaults to 16). See aws/aws-cdk#14389 for more motivation from the AWS CDK.

Our `yarn-upgrade` workflow is failing with:
```console
@lerna/package-graph@4.0.0 ✔
**ERROR** Failed to apply patch for package jsii-rosetta at path
node_modules/jsii-rosetta
This error was caused because jsii-rosetta has changed since you
made the patch file for it. This introduced conflicts with your patch,
just like a merge conflict in Git when separate incompatible changes are
made to the same piece of code.
```
Basically, its not able to apply the [rosetta patch](https://github.com/aws/aws-cdk/blob/master/patches/jsii-rosetta%2B1.28.0.patch) anymore since a new version of `jsii-rosetta` has been released which creates conflicts.
The new version of rosetta [addresses](aws/jsii#2816) the problem the patch was trying to solve, so it is no longer needed (yey).
