This switches stage2 to C and uses Jinja to change the C code based on flash settings from https://github.com/adafruit/nvm.toml. It produces the fastest settings for the given set of external flashes. Flash size is no longer hard coded so switching flashes with similar capabilities but different sizes should *just work*. This PR also places "ITCM" code in RAM to save the XIP cache for code execution. Further optimization is possible. A blink code.py still requires a number of flash fetches every blink. Fixes #4041
