Fix svg outline widths are incorrectly scaled (fix #11522)

SVG outline width sizes were not correctly calculated, and were
set to a constant value regardless of the rendered size of the svg
image. This meant that:
1. the rendered outline width was effectively randomly scaled
2. the width would change as the symbol size was modified

This change has some large flow on effects, eg:

- the large outline widths required to render an outline in <2.12
will now be drawn in their correct sizes, eg massive outlines. Projects
will need to be updated to reflect this.
- the default outline width set for the provided svg symbols (1 mm)
is much too large, so the symbols look bad with the default width.
This size needs to be modified in all the (~300 svg marker images)
- On the plus side, the long standing issue where most of the svg
symbols were rendered with white fill on white background and an
almost invisible black border is now fixed (refs #10908, #8538)

Remove default fill param from included SVG files if default is #FFF

using:
grep -R -rl \"param\(fill\):space:*#FFF\" | xargs sed -i -b 's/\(param(fill)\)\s*#FFF"/\1\"/g'

(refs #10908)

Remove default outline-width param from included SVGs if
default value is non 0

using the monstrosity:
zerowidth='!0'; grep -R -rl -P "\"param\(outline-width\) (?${zerowidth})(.*?)\"" | xargs sed -i -b 's/\(param(outline-width)\)[^"]*"/\1\"/g'

(fix #10908)
