[11.x] Allowing Usage of Livewire Wire Boolean Style Directives

Relates to #50994

Explanation

As we know, Livewire allows us to use some Boolean-style directives, that is, without any defined value, which is the case with directives such as: wire:poll, wire:loading, wire:loading.remove, etc. This PR aims to ensure that the use of these directives does not define their value as the name of the directive itself.

Before:

{{-- Using like this --}}

<x-fetch wire:poll />

{{-- Generates this HTML --}}

<div ... wire:poll="wire:poll" />

After this PR:

<x-fetch wire:poll />

<div ... wire:poll />

---

Although there are ways to deal with this - as mentioned by @driesvints in the issue, the work becomes overwhelming when we need to use directives like wire:poll (without specific value) several times.
