Revert #1629 - _Allow adding custom Macroable classes_

[erikn69]

Summary

There is no standard for "macroable", it should only work with the native Laravel one. (Alternative to #1706)

Example:

• briannesbitt/Carbon/Traits/Macroable.php
• filamentphp/filament/Concerns/Macroable.php#L17-L20

Even the author agrees that the macros for other "macroable" traits could not be obtained (#1629 (comment)).

Hey @barryvdh Thanks for your help and the merge. FYI, it's still not working with Filament, as I just saw they don't use the same macroable code as Laravel: Laravel:

Filament:

Hence, it's obviously not compatible with this package Alias::getMacroFunction function... 😞
Not sure whether you'd like to provide a special treatment for them?

@barryvdh that PR was merged causing many problems, please revert it 🙏
I also think I can improve some things here, but I depend on this

• Closes User defined Facades and Date macros #1704
• Closes Macros for Http facade doesn't work well #1702
• Closes Macros for DB facade doesn't work #1705
• Closes Http Macro doesn't work since 3.5.0 #1690
• Closes method added using mixin on Facade are not interpreted since 3.5.0 #1683
