Add more resource types to be translated

Before this commit, only gradients, palettes and potentially brush tips could be translated. This commit adds some other files types like .kpp presets, .kwl window layouts, .kws workspaces, .kgm gamutmasks, .png patterns, .myb presets and .svg symbol libraries and brush tips.

Test Plan

1. Extract i18n using the extracti18n.pl script before my changes to a file, then do the same thing but with my changes. Diff between those two files should show that I only added new strings, not removed or changed anything that was there before.
2. Look at the new strings and see that they are pretty (no extensions etc.).
