I think it's your custom module.so You need to search in app/Code , then if you need to override that xml you have to overwrite it in app/design.. — aravind, Feb 26, 2019 at 11:26

$block->getChildHtml('Cusomer_form_register_layyout3')

This is nothing but name of block which exist in layout file so you can search in layout(either in your module or design section).
$block->getChildHtml() used to fetch the content of phtml assigned with respective block name.
Here is detail description to add one extra tab in product detail page:
