fix(next-core): apply image-loader alias to the remaining context

[kwonoj]

What?

Fix custom image loader not being reflected in some contexts and running the default image loader when next.config.js is present. For Webpack, this alias is specified in createWebpackAlias (

next.js/packages/next/src/build/create-compiler-aliases.ts

Line 22 in 8d28d59

export function createWebpackAliases({

) and this setting seems to be context-agnostic in base (

next.js/packages/next/src/build/webpack-config.ts

Line 649 in 8d28d59

alias: createWebpackAliases({

).

Closes PACK-2509
