I was profiling and remembered GN hasn't turned on much CPU-specific code. I looked at zlib, then libpng, then libjpeg-turbo:
- zlib was easy but not useful. No routine we use in decoding changes significantly.
- libpng was easy and useful, and we were already using NEON filters on ARM.
- libjpeg-turbo requires yasm and is annoying.

This extends the pattern in freetype2 to expat, icu, libjpeg-turbo, libpng, libwebp, and zlib, and gives all these an arg to control which to use.
Homebrew doesn't have dng_sdk, piex, or sftnly, or I'd have done the same for them too.

Once you have downloaded an android NDK, you can set the ndk GN arg to use it.
E.g. my gn.args looks like:
is_debug = false
ndk = "/opt/android-ndk"
This should be enough to get you going for an arm64 build. You ought to be able to tweak that to other architectures by changing target_cpu to "arm", "x86", "x86-64", etc. That won't quite work until I follow this up a bit, but the skeleton is there.
This is enough to get me compiled, linked, and running to completion on my N5x.

This builds, links, and runs on Linux. Have not tried Mac.
I've tested is_debug={true,false} and is_component_build.
It's neat that the component build DM works, but it's also an indication I've missed an essential flag or two... it shouldn't work. :)
The GPU backend isn't working yet, but all the software configurations I've tried look good.
This fleshes out all the other parts of SkCodec too... I noticed we weren't able to decode gifs or webp.

- Make fiddle build on Mac (skipping GL).
- Now that we're building in SkCodec, we depend on libpng and libjpeg-turbo unconditionally, not just on Linux.
- Re-arrange third_party a bit so that our targets are Fuchsia/Chrome compatible.

This doesn't affect Chrome/Blink, so landing through the closed tree.
