refactor: improve resolving

[alexander-akait]

This PR contains a:

• bugfix
• new feature
• code refactor
• test update
• typo fix
• metadata update

Motivation / Use-Case

avoid unnecessary resolving for new URL syntax

Breaking Changes

• used new URL() syntax, instead import when esModules: true
• alias.resolve with false value now generate empty dataURI, please use url.filter to keep URLs as is
• ~ is depreacted but still supported, you can safely remove ~ from your code, due logic prefer relative then prefer absolute (only for esModules: true)
• css-loader will be faster if you enable esModules (true by default)

Additional Info

fixes #1246, only when you use esModules: true
