Add all svgs to org.eclipse.pde.ui bundles

This commit adds SVGs for all icons in the bundle `org.eclipse.pde.ui`
and `org.eclipse.pde.ui.templates` except for the following as these are
not available as SVG yet:

org.eclipse.pde.ui/bndtools/bndrun.svg
org.eclipse.pde.ui/bndtools/bundle.svg
org.eclipse.pde.ui/bndtools/database.svg
org.eclipse.pde.ui/elcl16/cleanmanifest.svg
org.eclipse.pde.ui/etool16/eclipse.svg
org.eclipse.pde.ui/obj16/eclipse.svg
org.eclipse.pde.ui.templates/etool16/e4.svg

I did not change occurrences of PNGs in classes like `ExtensionSection`,
`AboutSection` or `WindowImagesSection` in `org.eclipse.pde.ui` as this
would change business functionality and I don't know the side effects of
it or if they are even connected to viewing images in the IDE.

I did not change any references to `sample.png` or `eclipseXX.png` in
`org.eclipse.pde.ui.templates` as these are references to other bundles
or maybe placeholders.
