docs(usb): add ESP32-H4 support notes and pin map

Browse Source 
- usb_device: add esp32h4 DP/DM defaults (GPIO22/21) and "only:: esp32h4";
  add H4 PHY considerations; add H4 MSC write-speed table; generalize MSC SD
  note to {IDF_TARGET_NAME}; exclude tusb_ncm on H4
- usb_host: include esp32h4 in feature gates; add H4 PHY considerations
- usb_host_notes_dwc_otg: enable H4 by extending "only::" selector
- examples/usb: add ESP32-H4 row to DP/DM pin map
- docs_not_updated: drop H4 entries for usb_device, usb_host, and related
  usb_host notes now covered
- soc(esp32h4): set internal PHY mapping to DP=22, DM=21
