Remove unused constants.
Use ALL_CAPS for defines and kCamelCase for static const values.
Change some defines into static constants if they are not used in array sizes.

previously failures in the call to
VP8LBackwardReferencesTraceBackwards() would be ignored which, though it
wouldn't result in a crash, would produce non-deterministic output

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
for consistency. this mostly affects VP8Decimate(), ReconstructIntra16()
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 it's not available. Even if the value was discarded and
never used, some msan config were complaining about reading it
and passing it around.

Visual Studio added ARM64 support, but requires arm64_neon.h to be
included rather than arm_neon.h. Visual Studio 2019 addressed this so
we'll start with that version and leave a local adapter include for a
follow up.

after:
ece18e55 dsp.h: respect --disable-sse2/sse4.1/neon
WEBP_USE_* will be set when a module is targeting a particular
instruction set, e.g., sse4.1, and not overridden if WEBP_HAVE_SSE41 is
set, as previously this would ignore the case where the instruction set
was disabled via config.h and the HAVE macro was unset.
dsp.h not ensures WEBP_HAVE_* are set when WEBP_USE_* to cover cases
where the files are built without config.h.
Change-Id: Ia1c2dcf4100cc1081d968acb6e085e2a1768ece6
(cherry picked from commit 1fe3162541)
previously this would be overridden if the instruction set was enabled
via -msse4.1, __aarch64__, etc.
Change-Id: I51e87a7da7589c6093d260b848ab41d89ec7b990
similar to '* const', __restrict needs to be included in the
declaration to avoid warnings like:
src\dsp\alpha_processing.c(429): warning C4028: formal parameter 1
different from declaration
this change also moves WEBP_RESTRICT to dsp.h to avoid a circular
dependency between it and utils.h which already includes dsp.h
