[skia] Use Skia's clone of SwiftShader and speculative fix for broken build (#1576) 
Don't explicityly clone SwiftShader in the Dockerfile, since Skia
does that itself.
Also, make a speculative fix for a build issue where builders get
confused by the current working directory.

Build Skia with SwiftShader (#1573) 
This requires  building SwiftShader as well as changes to skia's
build. Reenables fuzzers that were disabled for AFL since we no
longer need to patch the binaries.
Also optimize invocations of git clone by adding --depth 1.

[skia] Disable AFL builds of mock gpu fuzzer (#1383) 
After building AFL fuzzers we will now check if they crash immediately before
uploading a build to CF. That means we can't build broken fuzzers or else
the entire build breaks.

Only build image_filter_deserialize_width for libFuzzer (#1218) 
The fuzzer's entire purpose is to use a libFuzzer flag that has
no equivalent in AFL. So only build it for libFuzzer.

[skia] Add an edge coverage version of image_filter_deserialize that uses edge coverage (#1215) 
Add another version of image_filter_deserialize (image_filter_deserialize_width)

Add a version of image_filter_deserialize that does not use hit counts as a
feature. This may reduce the chances that libFuzzer spends on pathological
executions it will reduce the fitness of loops and recursive code for testcases.

Name it image_filter_deserialize_width since this version cares about the number
of edges it hits (width) rather than the hitcounts on each edge (depth) like
normal fuzz targets.
