Add FAST_BOOT bitmask parameter

[rishabsingh3003]

Added a new FAST_BOOT parameter to avoid some startup blocking calls in hopes of getting quicker boots, which is important for some use cases.

I will update this bitmask to add more things.

In general this looks like a good idea. As we do this, if possible it would be good to consider whether we can implement the speedups for everyone thus avoiding the need for the option bit.

So for example, for the ESC calibration, don't we already have a bit to disable it? ESC_CALIBRATION = 9 (Disable). Maybe we could make that the default?

In general I agree the issue is that lots of our autotests seem to relay on specific timing startup and it is much easier (for now) to make this optional and then gradually change the defaults.
