Use individual board makefiles

[GrantM11235]

make <board> creates bootloader_only_binaries/<board>.bin by including boards/<board>.mk.

make all runs make <board> for every board in the boards/.

This dramatically simplifies the makefile and makes it much easier to maintain and add new boards.

This pull request (and each individual commit) should produce binaries that are identical to the master branch:

git checkout master
sh make_all.bat
md5sum bootloader_only_binaries/* > binaries.md5
git checkout board-makefiles
rm bootloader_only_binaries/*
make all
md5sum -c binaries.md5

Thanks

I'll try it on my PC

This seems a sensible improvement; is there anything blocking its merging? TIA!

[GrantM11235]

I just checked this again, it still produces identical binaries. In my opinion this is ready to be merged 👍
