v17 enum tree-shaking strategy not working on esbuild

[yaacovCR]

Hey folks,

The tree-shakable non-TS enum strategy for kinds introduced in:

• refactor: treeshakable kind enum #4270

and discussed in:

• Enums not tree shaking well #4253

appears to not work for esbuild: see demonstration

This appears to be due to the following known limitation within esbuild:

• re-exported namespaces cannot be tree-shaked evanw/esbuild#1420

This currently works in both latest rollup and webpack 5.

(Success with rollup and webpack 5 and failure with esbuild was also confirmed locally (not shown) within graphql-js by riffing of some of our newer integration tests,)

Not sure if this can be fixed by a change on our end, flagging it now and heading to bed. :)

Edited above, not sure if there is any known work around we could implement?
