First big changes in pulseaudio fork (lxpulseaudio)

[GermanAizek]

First big changes in my pulseaudio fork (lxpulseaudio)

New features for users

• By default sample rate 48000 Hz as on Windows 10/11 (for gamers, streamers and audio composers)
  
  Pulseaudio select number fragments and ms from available SIMD CPU (for old cpu and modern cpu)
  
  New dependency flag includes use OpenMP for modern cpu, for processors with one core it can hurt, but I don't have enough time to check it. (edit meson.build `required : true` on false for disable OMP. )

Optimizations for x64 cpu

• cpu-remap (Mono to Stereo remapping) using new AVX2 implementation (Coming soon AVX 128-bit for CPU without AVX2...)
  
  By default latency pulseaudio decreased ~22% for old and modern CPU
  
  51/52 cpu-mix-test showed decrease calculate time ~19%

New features for devs in ABI

• new function for get unsigned 16-bit tag struct pa_tagstruct_getu16() and read u16 read_u16()
