Subject: [PATCH] GCC: remove noexcept declaration in CrossVariantMojoAssociatedReceive/Remote

It breaks compilation of blink::WebServiceRegistrationObjectInfo that includes
WebServiceWorkerObjectInfo instance. This one uses default move constructor
without noexcept declaration, but has as members CrossVariantMojoAssociatedReceive
and CrossVariantMojoAssociatedRemote with noexcept declaration in move constructor.
declared noexcept.

As resolved in other places, noexcept is not really much useful with -fno-exception
and our codebase is not prepare to add it consistently. Clang will not report
exception declaration incompatibilities in case -fno-exception is used, but GCC
fails.
