vcl: detach usage and remove GraphicManager and GraphicCache
Also remove some GraphicObjectTest because they call into GraphicManager which now doesn't exist anymore. Change-Id: Ia434736d8611df629af3e897c878a7fb8bbe4706 Reviewed-on: https://gerrit.libreoffice.org/52243 Tested-by: Jenkins <ci@libreoffice.org> Reviewed-by: Tomaž Vajngerl <quikee@gmail.com>
