fix: Add complete class methods to prevent Intelephense conflicts

[erikn69]

Summary

Alternartive to #1695, #1696, Closes #1693

This PR fixes Intelephense issues by adding complete classes methods to the generated stubs.
It also works for other simpler IDEs, I tested it in NetBeans

Now could be

• include_complete_stubs => true //(default: false), would force map all the methods of the aliases
• include_complete_stubs => [Request::class, Arr::class] would force map only the listed aliases

Changes:

• Added new config option include_complete_stubs(OPT-IN, false as default)
