Subject: [PATCH] GCC: default move constructor of ServiceWorkerRunningInfo noexcept requires StrongAlias noexcept too.

Fix for this GCC compilation error:
../../content/public/browser/service_worker_running_info.cc:26:1: error: function ‘content::ServiceWorkerRunningInfo::ServiceWorkerRunningInfo(content::ServiceWorkerRunningInfo&&)’ defaulted on its redeclaration with an exception-specification that differs from the implicit exception-specification ‘’
   26 | ServiceWorkerRunningInfo::ServiceWorkerRunningInfo(
      | ^~~~~~~~~~~~~~~~~~~~~~~~

Problem comes from blink::ServiceWorkerToken move constructor being declared
noexcept, but its parent StrongAlias not having noexcept.

Fix making StrongAlias move constructor noexcept too.

Subject: [PATCH] GCC: pending fix for ServiceWorkerRunningInfo noexcept in move constructor

It is not enough to make StrongAlias noexcept. TokenType needs to also
provide noexcept move constructor.
