This brings minor size improvements because repetitive values in
the transform images are easily explainable through LZ77. Still,
it makes an upcoming pull request a bit more stable.
This is a rollforward of

This needs to be done with signed saturation as the sum may be negative.
fixes mismatch with C code after:
3bfb05e3 Add AArch64 Neon implementation of Intra16Preds

* changes:
Use QuantizeBlock_NEON for VP8EncQuantizeBlockWHT on Arm
Add AArch64 Neon implementation of Intra16Preds
Add AArch64 Neon implementation of Intra4Preds
Add a Neon implementation of Intra16Preds for use on 64-bit Arm
platforms. (This implementation cannot be used on 32-bit Arm
platforms as it makes use of a number of AArch64-only Neon
instructions.)

oss-fuzz does not support dynamic libraries so we stick to
static. But libtiff.a has undefined symbols on Ubuntu, so we
have to disable TIFF.

The lossless encoding speed-ups are:
- up to 1% with default parameters
- up to 4% in cruncher mode: -q 100 -m 6

Apply crop dimensions before calculating scaled width/height to ensure
the check against fuzz_utils::kFuzzPxLimit will use the same dimensions
as the decoder.

Also do not restrict the oss-fuzz script to libfuzzer:
this allows new fuzzer engines to try the script as is.
The libfuzzer restriction is done upstream anyway.

- the tests now build/run/check_build with libfuzzer on oss-fuzz
- centipede is removed as it builds/runs but do not check_build
(timeout due to arguments not parsed correctly)

fuzztest is compatible with libfuzzer in compatibility mode, and
fully compatible with centipede by default.
