This commit is intented to be enough to start the review process with maintainers to verify approach with
library and examples is the correct path, before adding additional examples and other parts.

 - Created TinyUSB library and Makefile for support library build
    - Added TinyUSB source files for device mode and MAX32 support
    - Added TinyUSB example projects verbatim as reference code. Not compiled in.
 - Added cdc_msc and cdc_msc_freertos examples for MAX32650
 - Moved existing MAX32650 MAXUSB example to subfolder in Examples.

* Update tinyusb build system integration

- Swap out Makefile for latest project "driver" Makefile.  The only
  difference here is that TARGET is floating.
- Simplify tinyusb.mk
- Add build-specific configuration to project.mk, and simplify
  IPATH/VPATH requirements
- Add clean.tinyusb
- Build library inside the tinyusb library by default
- Add default configuration directory

* Use override on PROJECT

 - Updated TinyUSB build system to incorporate FreeRTOS include folders
 - Updated existing MAX32650 examples for new build variables.
 - Added README to existing examples
 - Added HID and MSC example projects for MAX32650
 - Cleanedup .vscode folders to match existing MSDK examples.

 - Added example project (cdc_msc, cdc_msc_freertos, hid_composite, msc_dual_lun) for MAX32666
 - Relocated legacy MAXUSB examples to subfolder.

 - Added TinyUSB Examples (cdc_msc, cdc_msc_freertos, hid_composite, msc_dual_lun) for MAX32690
 - Moved MAXUSB examples to subfolder

 - Added TinyUSB Example (cdc_msc, cdc_msc_freertos, hid_composite, msc_dual_lun) for MAX78002
 - Moved MAXUSB examples to sub folder.

Updated TinyUSB to baseline against commit ca3925a (PR #2708) which merged MAX32 support into master.
