Add the job progress panel

This panel is displayed on click of the job toolbar icon.

This also changes the context passed into files.MenuManager to be the
activity context as the application context doesn't have the theme
information required for JobPanelController to inflate layouts.

Bug: 385841754
Test: atest -c 'DocumentsUIGoogleTests:com.android.documentsui.JobPanelUiTest'
Flag: com.android.documentsui.flags.visual_signals_ro
