Plugins: Remove `is_object()` check in `WP_Hook:build_preinitialized_hooks()`. 

This is a minor performance enhancement:

* If an object is passed, the call to `is_object()` will be redundant.
* If a non-object is passed, the `instanceof` operator (a variant of `is_a()`) will first [https://github.com/php/php-src/blob/f42992f/Zend/zend_builtin_functions.c#L630-L631 check if it is an object] before doing any further processing.

Therefore, no additional processing cycles should be wasted in both cases.

Follow-up to [38571].

Props bor0, johnbillion, davidbaumwald.
