[NuGet] Announce status messages using Voice Over

The status message that is displayed with the spinner is now
announced by Voice Over. When the status message is removed another
message is announced by Voice Over to say the loading has completed
or, if a search filter was entered, search was completed. If no
packages are found when searching this message is also announced
by Voice Over.

Fixes VSTS #1022830 - Accessibility: NuGet Packages: VoiceOver is
not announcing the status message.
