screenshot: Split out disabling cast button

Browse Source 
Screencasts can be disabled for various reasons:

 1. the service is not available (missing plugin etc.)
 2. screencasts are not allowed by the session mode
    (lock screen etc.)
 3. the UI is invoked in screenshot-only mode (portal)

Currently each of those conditions is handled in a different
code path, which means that later conditions can re-enable
the button.

There's also an inconsistency whether disabling the button
is done via visibility or reactivity, which still allows
toggling the hidden button via shortcuts (although a hidden
button means that screencasts aren't supported at all, so
nothing will be recorded in that case).

Address this by updating the button from a dedicated function.

Fixes: 671df28a50 ("screenshot: Only handle mode-switch shortcut when
supported")
