Previously, SkPngCodec assumed that the stream only contained one
image, which ended at the end of the stream. It read the stream in
arbitrarily-sized chunks, and then passed that data to libpng for
processing.
If a stream contains more than one image, this may result in reading
beyond the end of the image, making future reads read the wrong data.
Now, SkPngCodec starts by reading 8 bytes at a time. After the
signature, 8 bytes is enough to know which chunk is next and how many
bytes are in the chunk.
When decoding the size, we stop when we reach IDAT, and when decoding
the image, we stop when we reach IEND.
This manual parsing is necessary to support APNG, which is planned in
the future. It also allows us to remove the SK_GOOGLE3_PNG_HACK, which
was a workaround for reading more than necessary at the beginning of
the image.
Add a test that simulates the issue, by decoding a special stream that
reports an error if the codec attempts to read beyond the end.
Temporarily disable the partial decoding tests for png. A larger change
will be necessary to get those working again, and no clients are
currently relying on incrementally decoding PNGs (i.e. decode part of
an image, then decode further with more data).

This change is needed since once we start getting support for varrying of extensions
and newer version support in general, we need a common vulkan header to compile off of.
Otherwise we will run into problems if clients have older headers that don't include
functions/symbols we are trying to use.
Additionally it has the benefit of not needing to add if SK_VULKAN around code in
include which wants to use vulkan symbols.

I set -mdspr2 unconditionally on 32-bit MIPS builds only to not have to
deal with setting it conditionally on the source files specifically
requiring those instructions.
Since then, I've deleted all the source files specifically requiring
-mdspr2 (and -mdsp). No one understood them and they were only
accelerating really uninteresting cases, like 565 blits.
So, we haven't needed -mdspr2 anywhere for a while, and removing it
will unblock running these builds on the CI20 dev boards, which
support neither -mdsp nor -mdsp2.
