Bug: skia:10178
These functions can be performed generically using SkRasterPipeline
or skcms. Further, the reason we used a function pointer anyway was
so that we could call the same function on each row separately. But
libwebp's API doesn't let us do a single row at a time anyway.
Simplify this method by using readPixels when necessary and
skipping conversion entirely when possible.
Add support for encoding from unpremul 4444. It is simpler to support
it, and it's not obvious why we didn't support it before.
Keep the behavior of not supporting A8, and apply the same to the
other alpha-only formats. Note that we could support encoding such an
image to alpha, r=0, g=0, b=0, but I'd rather leave adding that
feature to a separate change, which enables it for all encoders (and
accounts for the internal use of PNGs as a round-trip for
kAlpha_8_SkColorType).
Add GMs to test the newly supported SkColorTypes.

Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

In SkEncodeImage and friends, treat quality of 100 as a lossless encode
when using kWEBP. This seems a good fit for the intent - which is
presumably to save the highest quality image. This also matches
Chromium's blink::ImageEncoder::ComputeWebpOptions, which treats a
quality of 1 (on a float scale from 0 to 1) as a lossless encode.
FWIW, Chromium has had this behavior since
https://codereview.chromium.org/1937433002, in response to
crbug.com/523098. The goal is to "maintain sharpness to
match the JPEG encoder behavior (use WEBP lossless encoding)".
Add a test to verify the new behavior. This requires making tests
depend on libwebp to use WebPGetFeatures, since the Skia API does not
provide a way to determine whether an encoded webp file was encoded
lossless-ly or lossily.

- Encoders and decoders always assume kIgnore.
- They are less opinionated about F16 and color space,
we just trust the color space that's passed in, and
put that directly in the image (no sRGB encoding).
- SkBitmap and SkPixmap read/write pixels functions were
defaulting to kResepct, those are now always kIgnore.
- Many other bits of plumbing are simplified, and I
added a default of kIgnore to SkImage::makeColorSpace,
so we can phase out that argument entirely.
- Still need to add defaults to other public APIs that
take SkTransferFunctionBehavior.
- This makes gold think that we've dramatically changed
the contents of all F16 images, but that's because
it doesn't understand the (now linear) color space
that's embedded. Once we triage them all once, they
will work fine (and they'll look perfect in the browser).
