[12.x] Improve @use directive to support function and const modifiers

[rodolfosrg]

What's New? 🎉

The @use directive in Laravel just got a major upgrade!
Before, it only supported two parameters: a path and an alias.
Now you can also specify function 🧩 or const 🔥 imports directly within Blade templates!

✅ Example

@use(function App\Helpers)
@use(const App\Constants\MY_LITTLE_CONST, MY_LITTLE_ALIAS)

✅ Grouped imports still work beautifully

@use(function App\Helpers\{foo, bar})
@use(const App\Constants\{FOO, BAR})

✅ Paths still work with or without leading slashes

@use(function \App\Helpers)

Why is this awesome? 🧠💡

• More readable 📝: No need for messy <?php tags inside Blade views!
• Fewer lines 🧹: @use keeps your templates clean and tidy compared to multiple PHP use imports.
• More idiomatic 🎨: Feels natural and consistent with Blade syntax, avoiding context switching between PHP and Blade.
• Blade power-up ⚡: Leverage PHP constants and functions elegantly without breaking out of your Blade flow.
• Future-friendly 🛡️: Makes Blade templates more maintainable and expressive!

TL;DR 🏎️

@use isn't just for classes anymore - now it's for functions and constants too!
Write cleaner, sharper Blade views without sacrificing PHP power! 🧙‍♂️✨
