[12.x] Add Cache::withoutOverlapping() to wrap Cache::lock()->block()

[mathiasgrimm]

Add Cache::withoutOverlapping() method

Description

This PR adds a new atomic() method to the Cache Repository that provides a cleaner API for executing callbacks within atomic locks.

Before

Cache::lock('my-lock-key', 600)->block(10, function () {
    // critical section
});

After

Cache::withoutOverlapping('my-lock-key', function () {
    // critical section
});

Method Signature

public function withoutOverlapping($key, callable $callback, $lockSeconds = 600, $waitSeconds = 10, $owner = null)

Parameters:

• $key - The lock key name
• $callback - The callback to execute within the lock
• $lockSeconds - How long the lock should be held (default: 600)
• $waitSeconds - How long to wait to acquire the lock (default: 10)
• $owner - Optional owner identifier for distributed lock restoration

Throws: LockTimeoutException if the lock cannot be acquired within $waitSeconds

Default Values

The defaults of 10 seconds for both $lockSeconds and $waitSeconds match the existing session/route blocking defaults in the framework (SessionManager::defaultRouteBlockLockSeconds() and Route::block()).
