[9.x] Add predefined_constants to reservedNames array

[AbdlrahmanSaberAbdo]

What

---

This PR is for adding predefined_constants to reservedNames array in a generator command. for example:

php artisan make:model __FILE__

Why

---

Using PHP keywords & constants as the name when using generation commands is not only bad practice, but it simply does not even work.

For example, if there's a developer who wants to create a model called __FILE__

Some could say:

"Developers should just be cautious and not use keywords when scaffolding."

I partially agree, but when you use the following generation command for example:

php artisan make:model __FILE__ -a

And now your project is polluted with a model class, factory, migration, and seeder, while the model isn't usable in the first place. It would be much better to disallow the scaffolding immediately and prevent this.

Note

---

I asked myself why developers even name classes with underscores but when I checked the reservedName array I found the __halt_compiler keyword prevented before so that encourages me to add predefined_constants in PHP to prevent it also.
