Rewrite SVG viewspec tests to not be fuzzer tests.

Rewrite SVG viewspec tests to not be fuzzer tests.

This patch adds five new tests for invalid viewspec values and removes
the flaky and slow viewspec parser fuzzer tests.

See the viewspec spec for more information about the values tested here:
https://svgwg.org/svg2-draft/single-page.html#linking-SVGFragmentIdentifiers

Note: We do not support viewTarget or zoomAndPan so these values are
just checked for parsing correctness and not behavior. The other
values (viewBox, preserveAspectRatio, and transform) are actually
tested to work.

Binary file support is temporarilly disabled due to a bug. Please commit blindly
the binary files first then commit the source change as a separate CL. Sorry for
the annoyance.
