x265: updated to 3.6

Version 3.6
===========

Release date - 4th April, 2024.

New feature
-----------
1. Segment based Ratecontrol (SBRC) feature
2. Motion-Compensated Spatio-Temporal Filtering
3. Scene-cut aware qp - BBAQ (Bidirectional Boundary Aware Quantization)
4. Histogram-Based Scene Change Detection
5. Film-Grain characteristics as a SEI message to support Film Grain Synthesis(FGS)
6. Add temporal layer implementation(Hierarchical B-frame implementation)

Enhancements to existing features
---------------------------------
1. Added Dolby Vision 8.4 Profile Support

API changes
-----------
1. Add Segment based Ratecontrol(SBRC) feature: "--[no-]sbrc".
2. Add command line parameter for mcstf feature: "--[no-]mctf".
3. Add command line parameters for the scene cut aware qp feature: \ 
"--scenecut-aware-qp" and "--masking-strength".
4. Add command line parameters for Histogram-Based Scene Change Detection: \ 
"--hist-scenecut".
5. Add film grain characteristics as a SEI message to the bitstream: \ 
"--film-grain <filename>"
6. cli: add new option --cra-nal (Force nal type to CRA to all frames expect for \ 
the first frame, works only with keyint 1)

Optimizations
---------------------
ARM64 NEON optimizations:- Several time-consuming C functions have been \ 
optimized for the targeted platform - aarch64. The overall performance increased \ 
by around 20%.
SVE/SVE2 optimizations

Bug fixes
---------
1. Linux bug to utilize all the cores
2. Crash with hist-scenecut build when source resolution is not multiple of minCuSize
3. 32bit and 64bit builds generation for ARM
4. bugs in zonefile feature (Reflect Zonefile Parameters inside Lookahead, extra \ 
IDR issue, Avg I Slice QP value issue etc..)
5. Add x86 ASM implementation for subsampling luma
6. Fix for abrladder segfault with load reuse level 1
7. Reorder miniGOP based on temporal layer hierarchy and add support for more B frame
8. Add MacOS aarch64 build support
9. Fix boundary condition issue for Gaussian filter
