Add menu for Nano with Optiboot bootloader

Since we are now factory flashing obtiboot, 115200 is the new default upload speed. Adding a new entry to CPU menu is more explicit than adding an "upload speed" menu, and the bootloader path can be updated too.

Fixes #4492

Just checked with the production team, the new boards have 0xDA as high byte 🙁 So the bootloader size is still bigger than needed... Leaving as is for the moment.

When this was released in 1.6.21, it broke the uploading to all my Nano's. At the time, I didn't know how to debug this problem, so I stayed on 1.6.20. Eventually, I got tired of seeing the "You have new boards and libraries" pop-up box on every sketch load, so I finally upgraded to 1.6.21 and decided to track down this problem. Here I am.

It looks like the solution is for me to manually select "ATmega328P (Old Bootloader)" in the Tools/Processor menu?

For future reference, is there some place where end-users can find the Release Notes, README, or something when a new core version is released? Your release process isn't too obvious to me.
