Message:

Options, Meta APIs: Check setting group exists before search in unregister_setting().

Checks if the given $option_group exists before searching for the $option_name. Sets the $pos to false, as array_search() returns false if the option name (needle) does not exist.

This changeset fixes 2 different PHP Warning|Notice scenarios:

1. When the global $new_allowed_options is null, fixes raising Trying to access array offset on value of type null PHP Notice (PHP 7.4) | Warning (on PHP 8).

2. When the global $new_allowed_options is an array and the setting group key does not exist, fixes raising "Undefined index: unknown_setting_group" PHP Notice (PHP 7) | Warning (on PHP 8).

For both scenarios, the array_search() is skipped and the $pos is set to a default of false, i.e. which is the value returned when array_search() is unsuccessful.

Props xknown, hellofromTonya, nicolefurlan, oglekler, SergeyBiryukov, shailu25.
Fixes #57674.
