Posts/Post Types: Introduce 'is_post_status_viewable ' filter in `is_post_status_viewable()`. 

Introduces a new filter 'is_post_status_viewable' which allows overriding the check.

The function's return signature is a boolean type. This commit ensures
the return signature remains unchanged by requirinng a strict boolean
type of the returned filtered value.

Why?
* To maintain this signature and backwards-compatibility.
* To future prepare for PHP 8.1 and beyond.

An explanation is included in the filter's DocBlock.

Follow-up to [50130].
