refactor: replace cache-loader with babel-loader's built-in cache

[sodatea]

It's supposed to have better performance.
See babel/babel-loader#525 (comment)

Besides, this improves webpack 5 compatibility as cache-loader is now
deprecated

Hello,

when this will be released ?

i have still the issue on 4.5.11 :

npm WARN cache-loader@4.1.0 requires a peer of webpack@^4.0.0 but none is installed. You must install peer dependencies yourself.

├─┬ @vue/cli-plugin-babel@4.5.11
│ └── cache-loader@4.1.0 
└─┬ @vue/cli-service@4.5.11
  └── cache-loader@4.1.0  deduped

.nvm/versions/node/v14.15.4/lib
└── @vue/cli@4.5.11

thanks
