Fixing RAM calculator and reduced actual SRAM usage

- Changed static variables to const that should have been const
- Updated CMake files to prepare for MCHCK custom bootloader
- Changed the USB ID numbers and ID number for bootloader
- Only generate DFU or Teensy binary image, not both
- Fixed RAM and FLASH calculator
- Added missing license in delay.c/h (much of it was taken from Teensy source though I've changed a bunch of it)
- Prepared mk20dx.c for upcoming bootloader addition
- mk20dx.h cleanup
- Reduced the MCHCK based flash size for the application image (bootloader changes requires more flash space)
- Fixed bugs in macro.c
- Added keyHold cli command
- Added show pending events debug message for PartialMap macro module
