This also adds a little helper to fuzz that allows us to see what

This is the first step in getting a SwiftShader fuzz target.
To prove that this works, simply download this patch and run:

Of note, this is a breaking change to the fuzzed format
for any canvas fuzzers. I've updated the seed corpora to match
but any repro cases predating this will need to have the a single
byte added to the front of the test case:
echo -n -e '\x00' | cat - file > outputfile

This also includes a helper "fuzzer" for making a corpus.
Point it at an image or folder of images and it will
decode those images and write the SkPixmap's bytes to
disk, such that the fuzzer will be able to read in
those bytes as if it had decoded the image (or gotten
it from another source).

This reverts the revert 9ff8c8c073.
Original:
This is a performance-only hint that no one but fuzzers
is using. It's even explicitly filtered out in Android.
The fuzzers have noticed they can trick us into allocating
uninitialized memory and treating it as opaque, blending
uninitialized pixels, etc.
Since no one's using this, we can just kill the bit.

After this CL, we have 3.5 options for fuzzing ImageFilter
1. Create it from API calls and then draw it
fuzz -t api -n ImageFilter -b [input]
2. Deserialize a fuzzed stream into an ImageFilter (this is
what Chromium's filter_fuzz_stub does)
fuzz -t filter_fuzz -b [input]
3. Create an ImageFilter from API calls, serialize it, apply
some mutations to the stream, deserialize it, then draw it.
fuzz -t api -n SerializedImageFilter -b [input]
3.5 Create ImageFilters as part of our more general canvas
fuzzers.
fuzz -t api -n RasterN32Canvas -b [input] (and others)
Previously, the SerializedImageFilter had its own, slightly
stale and prone to stack-overflow way of making an image filter.
This CL re-uses what we already do for Canvas fuzzing and removes
that dead code.
Additionally, there is a way to easily generate a corpus
for the filter_fuzz type, via SerializedImageFilter.
