Move Microphone Audio Analysis to Worker Threads

[dgruss]

1. Introduced Worker threads for Audio Analysis and decoupled them from the GUI drawing (in the main thread)
2. UDraw.pas and UGraphicClasses.pas refactored to use the new threaded audio worker, per-player shared state, renderer copies data instead of locking, and particle effects protected with locks
3. Added a flag in the config.ini: in [Record]: WorkerInterval with default 5 (meaning 5ms). This is a trade-off between lag and CPU load. take into account that so far the interval was basically 16.67ms. 5ms is a significantly lower latency

Copilot was used for parts of the the code.
