boards: st: nucleo_l496zg: add zephyr_udc0 and hsi48 dt nodes

Add Zephyr UDC (USB Device Class) and clk_hsi48 (hi-speed internal 48 MHz) devicetree nodes so that the nucleo_l496zg board works with other USB DC samples and tests. Update the board yaml description to indicate usb and usb device roles are supported. Signed-off-by: Chris Friedt <[email protected]> (cherry picked from commit 3a07c9f)
