cdc device app rename CDCD_APP_BUFFER_SIZE to SERIAL_BUFFER_SIZE

cdc host app add SERIAL_BUFFER_SIZE for buffer constant, add cdc data receive if cb with TUSB_EVENT_XFER_ERROR
minor change to keyboard & mouse host app
add ASSERT_FAILED & ASSERT_FAILED_MSG
add cast to fix IAR build error with dcd_lpc43xx.c

FreeRTOS
- merge FreeRTOSConfig for m0, m3, m4
- re-implement application hook
- support portmacro.h for m0

### Serial
A virtual serial of CDC-ACM is supported, the host demo will echo back any thing it received from the device. So if you use the tinyusb device stack with CDC enabled to test with, you should modify it a bit to constantly send somethings (otherwise 2 demos will wait for each other).
A virtual serial of CDC-ACM is supported such as those built with tinyusb device stack. The host demo literally does 2 things
- Echo back any thing it received from the device to the terminal
- Receive data from terminal and send it to device.
Notes: FTDI is a vendor-specific class, which is not currently supported.
