Remove usused direct dependencies on webpack

[trivikr]

Describe the Feature

The direct dependencies for webpack were added on migrating from "react-scripts" in d6ec627.
However, they weren't removed when we target moved to expo in #288

The following dependencies can be removed as they're imported elsewhere:

• babel-loader
  • Now imported from @expo#webpack-config#babel-loader
  • No direct use in webpack config.
• babel-plugin-react-native-web
  • Now imported from @expo#babel-preset-expo#babel-plugin-react-native-web
  • No direct use in webpack config.
• html-webpack-plugin
  • Now imported from @expo#webpack-config#html-webpack-plugin
  • No direct use in webpack config
• webpack
  • Now imported from @expo#webpack-config#webpack
• webpack-dev-server
  • Now imported from @expo#webpack-config#webpack-dev-server

Following dependencies can be removed as they're no longer used:

• @tsconfig/react-native
• url-loader
• webpack-cli

If you remove them, please do verify that the build actually works — see #6459 for context.
