Add Missing SVGs to Platform UI Bundles

[Michael5601]

This PR adds all missing SVG to Platform UI Bundles.

All added icons were either created by me or copied if I found a duplicate with another name.

See this PR for a description of how I created the wizban icons.

I also added SVGs for the folder org.eclipse.ui.browser/icons/clcl16 which was forgotten before. These SVGs already existed but I could not find a place where they are used. For for the sake of completeness I added them nevertheless.

All missing SVGs are documented in this issue.

are don't you also add Wizban SVGs?

They are more complex than normal icons so it requires more work to create every icon.
I will also add them soon but wanted to focus on the low hanging fruits at first.
Also I don't know how long it will take to create the wizban icons.

Understood.
But can't you use the exisiting SVGs for them?

See comment #2970 (comment)
There are no SVGs for the following three icons in the bundle org.eclipse.ltk.ui.refactoring:

wizban/apply_rescript_wiz.svg
wizban/create_rescript_wiz.svg
wizban/show_history_wiz.svg

So these need to be created.

Do I miss something here?

I want to update my comment on this:
I found a fast way to create the wizban SVGs with only minimal drawbacks as described in PR by redrawing the bitmap in Inkscape.

I created the missing wizban icons for all Platform bundles and will proceed to create them in this PR for Platform UI bundles too.

Thank you for providing the SVGs!
In general the PR looks good. I just saw that the SVGs in org.eclipse.ui.browser are already referenced in code even though they did not exist, so it makes sense to have them in as soon as possible.

I am a bit concerned regarding the wizard banner icons: they are pretty huge (almost 1 MB) and they seem to be no proper vector graphics but just the original pixels represented as vectors. This, in my opinion, leads to even worse results when they are rescaled, as no anti-aliasted scaling is performed. See the scaled PNG (left) and the scaled SVG (right) in the following screenshot:

So I propose to exclude the wizard banners for now and find a proper way of replacing them with SVGs.

I've removed the wizard banner icons for the mentioned reasons again to make this PR ready to merge. We should have a separate look at them.

See eclipse-platform/eclipse.platform.images#144. There is have created SVGs for two of them.
