QmlDesigner: Support updating imported assets

Browse Source 
Added support for overwriting file-based assets such as images when
an asset with the same name is imported to the same location.

Assets tab will now also refresh its icons if underlying files are
modified. Added local caching of icons to avoid regenerating unchanged
icons. Also added bit of a delay before responding to a file system
change, which should improve performance when multiple assets are
imported at once.

Fixes: QDS-3644
