chore: Update dependency webpack to v5

[Nic128]

#1624

Let's try webpack 5 again, at this point every plugin/loader have compatibility. This PR contains the content from these two branches.

• Initial work to support Webpack 5 #1584
• https://github.com/neutrinojs/neutrino/compare/webpack-5

TODO:

• Infinite polling loop fix in webpack (HMR with node) fix hot/poll, hot/condition, hot/only-dev-server infinity recursion webpack/webpack#13877
• webpack-dev-server 4 https://github.com/webpack/webpack-dev-server/blob/master/migration-v4.md
• Webpack-chain v7 support webpack 5.x webpack-chain#297 (Or use @gem-mine/webpack-chain, which has the PR content)
• Karma-loader to v5 (Problem with shimming assert and process)
• [webpack-cli] Error: [VueLoaderPlugin Error] No matching use for vue-loader is found.

Alternative, we could release v10 alpha. One step in the v10 milestone, figure it out as we go. https://github.com/neutrinojs/neutrino/milestone/7

Hi! Thank you for the PR.

In order to move this forwards:

1. CI on this repo needs migrating away from Travis CI (since there are no credits left) - there is a WIP in GitHub actions #1663 but it has stalled
2. webpack-chain needs webpack 5 support first

[Nic128]

Ported the CI changes from #1663.

Ported the CI changes from #1663.

Thank you for looking at the CI changes. Could you move them to their own PR? I'm a fan of keeping PRs to be about one change at a time, and this PR is already pretty large (+1,104 −1,304) :-)

[Nic128]

Created a new PR with just the CI changes. #1675

It's possible some of the compilation problem I'm having will be solved when webpack-chain gets the webpack 5 support.

[Nic128]

The VueLoaderPlugin problem is eluding me. I'll need help. Hopefully, when upgrading webpack-chain, it'll resolve itself.

Edit: Upgrading webpack-chain is not the problem.

[Nic128]

Got passed the vue-loader problem.

[Nic128]

@edmorley The pipeline is now green, please review.

@Nic128 Sorry for the delay - busy + I don't use this project any more.

As mentioned in #1674 (comment) a pre-requesite for adding support for webpack 5 to Neutrino, is for webpack-chain to support webpack 5 first.

That work is being tracked here (help needed, since I won't be working on it):

Many thanks!

I have forked/published this branch for my own private usage and found bugs along the way. I'll update this PR when I find them.
