Adds support for user-defined wrappers in the SDK (#6370)

## What's the problem this PR addresses?

At work we're patching the SDK files to also send monitoring information
to our servers (so we can know how much time TS takes to run within
VSCode). This makes updating the SDK a little difficult, as we need to
remember to re-add the patched code after each update.

## How did you fix it?

The SDK will now automatically require the optional `user.sdk.cjs` file
if present, which must be located next to the file to patch.
