[CI][Proposed] CI should link libsvg statically

[citelao]

We should explore linking libsvg statically if that makes draw_svg easier to run.

We may need to link other libs statically if we want draw_svg to be truly redistributable:

$ otool -L util/draw_svg                                                                 
util/draw_svg:
	/usr/local/lib/libsvg.1.dylib (compatibility version 2.0.0, current version 2.0.0)
	/usr/local/opt/jpeg/lib/libjpeg.9.dylib (compatibility version 14.0.0, current version 14.0.0)
	/usr/local/opt/libpng/lib/libpng16.16.dylib (compatibility version 54.0.0, current version 54.0.0)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 904.4.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1292.60.1)

Follow-up from #31.

I also wonder if we can disable image processing in libsvg to reduce dependencies further, since we'll never use it.
