Update libjpeg-turbo to v2.0.5

Update Chromium's copy of libjpeg-turbo to the latest stable upstream
release (v2.0.5) and reapply our local changes documented in
README.chromium. This update addresses three CVEs - CVE-2018-19664,
CVE-2018-20330, CVE-2018-20330 - that do not affect Chromium. The
fixes do, however, satisfy UBSan - allowing Chromium's libjpeg-turbo
to be used in AOSP.

Cherry-pick one additional change[1] from upstream to prevent AArch64
Windows builds from failing.
