`_wp_array_get()` is an expensive function, and it's called thousands of times on each page view on the front end. While the function performance was slightly improved in #58376, it is still called more times than it should be. This commit aims to further optimize its usage: * In many cases, `_wp_array_get()` can be replaced with a much simpler and faster `isset()` check. * The `isset()` function is capable of checking nested arrays, so `isset( $foo['a']['b']['c'] )` will return false even if `$foo['a']` is unset, without throwing any errors or warnings. * When `_wp_array_get()` cannot be directly replaced with `isset()`, it would be good practice to wrap it in an `isset()` function so that `_wp_array_get()` only runs when it needs to. Original PR from Gutenberg repository: * [https://github.com/WordPress/gutenberg/pull/51116 #51116 Performance improvement: Reduce the use of the _wp_array_get() function] Follow-up to [55851], [56382].
