Building ffmpeg with x265 NEON arm64 cpu acceleration support

Current static binaries do not target https://bitbucket.org/multicoreware/x265_git/issues/563/patch-neon-arm64-improvements which can be identified

Before

x265 [info]: using cpu capabilities: none!

[libx264 @ 0xaaab0a5fc000] using cpu capabilities: ARMv8 NEON

After

x265 [info]: HEVC encoder version 3.5+1-f0c1022b6
x265 [info]: build info [Linux][GCC 9.3.0][32 bit] 8bit
x265 [info]: using cpu capabilities: NEON

[libx264 @ 0xaaab0a5fc000] using cpu capabilities: ARMv8 NEON

When buidling, do not count on apt, everything is old as hell. Target master @ HEAD

You're a hero! Thanks so much! It's so hard to find info on how to do this on Linux (I'm using OCI free tier lol but hey it works with ARM!). Cheers 🥂
