Fix: Waveshare S3 Touch LCD 2 Windows connectivity & USB detection

Disable native hardware USB JTAG interface in favor of TinyUSB CDC stack
to resolve driver enumeration issues on Windows hosts.

Updates:
- configs/sdkconfig_display_waveshares3_touch_lcd2.defaults: Switch USB stack
- main/power/wslcdtouch2.inc: Use TinyUSB tud_mounted() for reliable power detection
