backport change to webpack 4 version

#1678

If we want to merge and release this we'll also need to migrate this branch to use trusted publishing

I'm considering adding webpack 4 support back directly and not just on 8.x. Could you confirm if the branch in this pull request works for you? #1697

If you yarn build you should be able to plug it into your project and test easily

I've test this branch's build, but build with failure because of different source-map dependency version used (It's 0.6.1 in my project, but ts-loader needs 0.7.x).
There are some errors as follows.

error  in ./src/xxx/xxx.vue?vue&type=script&lang=ts
Syntax Error: TypeError: sourceMapConsumer.destroy is not a function
    at Array.forEach (<anonymous>)

Syntax Error: TypeError: module.addError is not a function
    at Array.forEach (<anonymous>)

Ah thanks - let me investigate!

[johnnyreilly]

Can you confirm which specific version of webpack 4 you are using please? Also, where is your version of source-map coming from? 0.6.1 I mean.

I've updated the branch version to guard against unusable versions of source-map - this should resolve your situation I think. I'm still curious as to what brought source-map@0.6.1 into your project?
