Message:

Login and Registration: Introduce is_login_screen() function.

This should help determine whether the current request is for the login screen.

While it does not save a lot of lines of code, including this function in core aims to save developers some time that would otherwise be spent investigating the most reliable way to solve this problem.

Implementation details:

• By checking wp_login_url(), the function accounts for custom login locations set via the login_url filter.
• By checking $_SERVER['SCRIPT_NAME'] directly, instead of did_action( 'login_form_login' ) or $pagenow global, the function can work as early as possible, for example in a must-use plugin.

Follow-up to [2481], [6412], [12393], [12732], [15558], [15481], [15746].

Props dcowgill, scribu, donmhico, iandunn, wonderboymusic, nacin, robmiller, kitchin, chriscct7, tazotodua, davidbaumwald, SergeyBiryukov.
Fixes #19898.
