fix(bun): Support application builds with Bun

[octet-stream]

Overview

Fixes #5917 (partially)

While Qwik has adapter for Bun, there's no support for running Qwik's CLI via Bun itself. Because of this developers must depend on Node.js during deployments just to build their applications even if they don't use it on their servers.

• Docs / tests / types / typos

Description

This PR fixes support for Bun in Qwik by just removing bun from the results of getEnv function in packages/qwik/src/optimizer/src/platform.ts. I am not quite satisfied with the solution, but it works. Still, I will be much appreciated if somebody helps me find a better solution, because I am not much familiar with the codebase.

In addition, this PR limits the number of workers for SSG, because otherwise the build will just hang without any progress. I wasn't able to properly isolate this bug and versify whether it is an issue with Qwik or Bun itself, so I just added the limit. The fact that the same code works in Node.js suggest that it can be on Bun's side, so I will report this issue to them and we'll see.

Lastly, this PR adds another place where we patch TextEncoderStream for bun, because bun does's have their implementation.

Also, since Qwik already uses polyfills in other places, this is something that needs to be better organized. I suggest we add a function that will (conditionally) apply all needed polyfill. You can look it Remix as the example: https://remix.run/docs/en/main/other-api/node#polyfills - they have a function installGlobals that does the same thing.

Use cases and why

Expected behavior was: bun run --bun build is able to run just as pnpm build without any issue

Actual behavior was: bun run --bun build fails with the error saying that the platform is not supported.

Currently to work around this issue, I had to setup Node.js in one of my Docker layers just to build my application during deployments.
