stm32l4: Set proper USB and HAL tick interrupt priorities for L433

[devin-ai-integration]

USB Power Management Implementation for STM32L433

This PR implements proper USB power management for the STM32L433-based Cygnet board:

1. Sets USB interrupt priority to 1 for STM32L433
2. Lowers HAL tick interrupt priority to 2 to ensure proper USB operation
3. Adds CRS configuration for HSI48 clock to maintain USB clock synchronization
4. Implements USB suspend/resume hooks for power management
5. Updates TinyUSB submodule to include power management support

These changes improve USB stability and reliability on the Cygnet board by:

• Ensuring USB interrupts have higher priority than system tick
• Maintaining proper USB clock synchronization via CRS
• Implementing proper power management during USB suspend/resume
• Following STM32L4 best practices for USB configuration
