Update libjpeg-turbo to v2.0.90 (2.1 beta1)
Update Chromium's copy of libjpeg-turbo to the latest upstream
release (v2.0.90) and re-apply our local changes documented in
README.chromium.
Cherry-pick two additional changes from upstream to fix bugs found
by fuzzers:
1) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/ccaba5d7894ecfb5a8f11e48d3f86e1f14d5a469
2) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/c7ca521bc85b57d41d3ad4963c13fc0100481084
Significant changes provided by this update:
1) A large performance boost to JPEG encoding due to an improved
Huffman encoding implementation.
2) The complete removal of Arm Neon assembly code. This allows Arm's
control-flow integrity security features (Armv8.3-A Pointer
Authentication and Armv8.5-A Branch Target Identification) to be
switched on with the appropriate compiler flags.
