Posts: Add filter to allow overriding `post_password_required` return 

Post Passwords are incredibly inflexible. One Password per site at a time and other limitations that can't really be changed without a backwards compatibility break.  This adds the ability for sites to change the password behavior such as doing per post passwords or allowing multiple passwords to be set in a browser. The possibilities are YUGE.

Additionally, it allows for a behavior other than returning a html form when a password is needed. This is important for non website use cases (such as in a restful API).

Fixes #38056. See #16483.
Props rmccue.
