Customize: `option_{$option}` filter applied with a missing parameter

[dlh]

WP_Customize_Widgets::capture_filter_pre_get_option() applies the option_{$option} filter to the captured value, but without the second $option parameter added in WordPress 4.4.

The missing parameter has the potential to generate fatal errors in PHP 7.1 and above from uncaught ArgumentCountError exceptions if a function is hooked to the filter that accepts both parameters.

The attached patch would add the second parameter to the apply_filters() call.

[43611] needs to be reverted from the 4.9 branch. This issue should then be milestoned for 5.0.1.

In 43701:

Customize: Revert [43611] from the 4.9 branch.

This change is out of the 4.9.x scope, and will be reintroduced in 5.0.x.

See #44770.

In 44387:

Customize: Pass missing parameter to dynamic option_{$option} filter in WP_Customize_Widgets::capture_filter_pre_get_option().

This prevents a potential fatal error from an ArgumentCountError exception in PHP 7.1 or greater

Props dlh.

Merges [43561] to the 5.0 branch.
Fixes #44770.
