Bug 1483957 [wpt PR 12531] - HTMLScriptElement text attributes modified to accept TrustedTypes, a=testonly

Automatic update from web-platform-testsHTMLScriptElement text attributes modified to accept TrustedTypes

HTMLScriptElement::text() and setText() functions modified to accept
TrustedScript as an argument.
Added HTMLScriptElement::innerText and HTMLScriptElement:textContent
attributes to override existing implementations in HTMLElement
and Node, and to accept TrustedScript.

Changed HTMLElement::innerText and Node::textContent .idl definitions
and adjusted setters and getters to accept TrustedScript.
