Add a tinyusb_driver_uninstall to tinyusb.c (IEC-41)

[johnboiles]

This makes it possible for user code to work around the bug where the USB/JTAG interface cannot be re-initialized after calling tinyusb_driver_install even if the chip is restarted with esp_restart (https://github.com/espressif/esp-idf/issues/9826#issuecomment-1694089147).

Currently user code cannot do this without a modification to tinyusb.c since there's no way to access static usb_phy_handle_t phy_hdl; outside of that file.

With this change, user code can run the following to deactivate TinyUSB and bring back the USB/JTAG interface.

tinyusb_driver_uninstall();
usb_phy_config_t phy_conf = {
    .controller = USB_PHY_CTRL_SERIAL_JTAG,
};
usb_phy_handle_t jtag_phy;
usb_new_phy(&phy_conf, &jtag_phy);
