Update VSCode & Makefile project generators

[Jake-Carter]

This PR updates the Visual Studio Code and Makefile project generators.

• VSCode generator has been updated to v1.5.0
• Makefile generators have been updated to the latest project.mk-based system.

Summary of changes:

• Update the izer's copy of the VS Code README to reflect the new build system

• Minor VS Code bug fixes/tweaks.

  • Add flash & run utility
  • Add erase flash utility
  • Fix typo in RISC-V launch profile
  • Move program counter to reset handler after resetting micro and launching debugger. Allows for smooth debugging of .elf files on parts with a secure bootloader.

• Support the --override operator from the VSCode and Makefile generators.

• Add new Makefile generator to izer/assets.py.

• Modify max7800x.py back-end to use new Makefile generator for M4-core projects. RISC-V projects will still use the old combined .elf Makefile system.

• [x] bash gen-demos-max78002.sh --overwrite (test-gen-demos-max78002.txt)
