Add allow unload=* to allowlist for some non-iframe frames.

With unload deprecation, it becomes impossible to use unload in
<frame>, <embed> and <object> because there is no way to set an allow attribute on them. This change adds an unload=* to their allowlist, meaning that unload will be allowed if both

• it's allowed in the parent
• the child sets the correct Permissions-Policy header

The unload feature has has no effect unless unload deprecation is enabled.
