Bug: chromium:922430
Bug: b/135180511
Chromium has diverged from upstream libjpeg-turbo in order to take
advantage of SIMD optimizations that have not yet been merged into
upstream. Android is also interested in using these. Switch to the
version with the optimizations in order to test them.
Chromium has its own jconfig.h and jconfigint.h, so ours are never used
after the switch. Remove them. The only Skia-specific modification to
these files was to define flags to enable arithmetic encoding. Move
them to BUILD.gn, so they're still applied. Also remove jsimdcfg.inc,
which is currently unused. (It appears to be only for x86/x64, where we
are not building SIMD anyway.)
Update BUILD.gn to build SIMD files on arm. The existing ones have
moved, and there are new ones to build, too.
