Description

Fix #4513

Disable cache-loader since it will omit url-loader/file-loader, this behaviour will lead to the fonts/images/vides which are less than 1K cannot be bundled.

And also webpack5 will be release soon, it will support cache feature internally, so it should be fine that apply current change for now.
