usb_usb: Add options for disabling blocking loops

USB startup wait loop delays UHS2 Task() starting for a while
like 200-600ms and USB suspend loop blocks the Task() while power
saving like 15-17ms. These loops may cause keyboard enumeration
failure, perhaps. Not confirmed it yet though.

#define IS_COMMAND() (keyboard_report->mods == (MOD_BIT(KC_LSHIFT) | MOD_BIT(KC_RSHIFT)))
// Disable power saving in USB suspend loop but remote wakeup is still valid.
// This allows keep USB::Task() going during suspend without power down time delay.
//#define NO_SUSPEND_POWER_DOWN
// Disable USB startup wait, which can delays starting UHS2 Task() for 350-600ms.
//#define NO_USB_STARTUP_WAIT_LOOP
// Disable USB suspend loop, which blocks UHS2 Task() while power saving.
// Note that this also disables power saving and remote wakeup from keyboard completely.
