Implement memory device

The memory device is fully implemented, with 3MB of heap memory.

This commit is a bit messy, additional changes are:
- The program memory and program counter in each Bedrock struct have
  been moved to a dedicated struct to prevent a name collision with the
  memory device
- The run_bg and debug functions have been moved to core.c and debug.c
- The blank screen colour has been changed back to black
- No second program runs on the sub screen by default
- The number of Bedrock instances to run has been parameterized
