refactor: resolveExports

[sapphi-red]

Description

At the time I created #10683, I was going to propose changing resolve.conditions's default to ['production', 'development', 'module', 'node', 'browser', 'import', 'require'].
This way people can remove default conditions. (The implementation will be like overrideConditions that I implemented in #10683)

But I realized there's a problems with this.
It's not possible to make #9860 work. Even if resolve.conditions was set to ['node', 'import', 'require'], node condition won't be used for targetWeb.

This PR just cleans the logic around this as I didn't come up with a solution.

  const conditions = [...additionalConditions].filter((condition) => {
    switch (condition) {
      case 'production':
        return options.isProduction
      case 'development':
        return !options.isProduction
      case 'import':
      case 'module':
        return !options.isRequire
      case 'require':
        return options.isRequire
    }
    return true
  })

  return _resolveExports(pkg, key, {
    conditions,
    unsafe: true

This is what I was going to propose.
