Editor: Reduce the use of the _wp_array_get() function to improve performance.

_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:

#51116 Performance improvement: Reduce the use of the _wp_array_get() function

Follow-up to [55851], [56382].
