It's self contained apart from a dependency on src/webp/types.h and src/dsp/cpu.h
For now it's only set up as an internal library, not an installable one.
Webp doesn't depend on it yet, the code is only duplicated.

results in code layout changes, a couple fewer instructions; some of the
smaller functions were unaffected as they were inlined, but are updated

and ReconstructUV().

A WebPPicture instance is necessary to call WebPReportProgress() which
sets WebPPicture::error_code so as well use WebPEncodingSetError() to
record errors too, instead of functions returning a WebPEncodingError.
However there must be one WebPPicture instance per thread, with error
codes merged at sync time. A mutex could simplify that but it is not
the objective of this change.

When using CMake the `<prefix>/usr/share/WebP/cmake/WebPConfig.cmake` gets
used to get the names of the libraries to link against.
Since version 1.2.1 of libwebp, libwebpmux is on by default.
This causes a linker error because the linker arg should be `-lwebpmux`
instead of `-llibwebpmux`.
This is fixable by renaming `libwebpmux` to `webpmux` in a few places.
This was identified after an update to 1.2.1 of libwebp in the OpenWrt
project:
https://github.com/openwrt/packages/pull/16766
Internally in OpenWrt, this was patched here:
https://github.com/openwrt/packages/pull/16784
