hathach ea5b8d677f dcd/ch58x: drive CH582/583 with shared dcd_ch32_usbfs.c ...

Replace PR #3515's separate dcd_ch58x_usbfs.c / hcd_ch58x_usbfs.c with the
shared WCH USBFS device driver (combined per-endpoint control, like CH32V103),
adding two CH58x-specific behaviors guarded so CH32V103/V20x/V307 are unchanged:

- CH32_USBFS_EP_MANUAL_TOG: CH58x's hardware AUTO_TOG does not stay in sync, so
  the ISR toggles DATA0/DATA1 manually and discards toggle-mismatched OUT
  packets. Fixes multi-packet bulk-IN (e.g. MSC READ10) that otherwise hung.
- CH32_USBFS_EP4_SHARES_EP0: EP4 has no DMA register and overlays EP0's region
  (EP0[0:63] + EP4 OUT[64:127] + EP4 IN[128:191]); add a 192-byte shared buffer
  and buffer-pointer helpers (transparent for the other parts). Fixes
  cdc_dual_ports (Port1 is on EP4).

Add the ch582m_evt board. Device only on USB0 (rhport 0): the shared
hcd_ch32_usbfs.c is CH32V20x-specific and cannot drive CH58x, so host / USB2
(rhport 1) is left commented out in the BSP for easy re-add.

Verified on ch582m_evt via local HIL: all device examples pass.
