Initial Commit for MAX32 Support

Initial commit for the port of TUSB to MAX32xxx parts, staring with MAX32690
 - Added dcd_max32.c (based on dcd_musb.c) for interfacing with the peripheral
 - Added MAX32690 part family support
 - Added max32690evkit board support
 - Updated examples for unique EP number requirement
 - Updated get_deps.py to fetch the MSDK

Known Issues / Additional Testing Required
 - msc_dual_lun only shown 1 volume on Windows
 - USBTMC does not have a valid Windowsdriver
 - DFU does not have a valid Windows driver
 - WebUSB is "Device not Recognized"
 - Need to test build scripts with IAR and Clang
