Prepare a system to embed bootloader version according to model type in core

[TychoVrahe]

Currently we only have a bootloader binary for model T in Core source. We will need to design a way to do it for additional models. Obviously a solution like bootloader_T.bin and bootloader_R.bin is possible, but maybe there might be a better way to do it? something that will not bloat the repo over time with binaries, like pulling the bootloader binary from CI during build or something?

bootloader_T.bin and bootloader_R.bin is possible

+1

The binaries are really small, there is no need to over-optimize things right now. Later, we could be considering using git-lfs, but I don't think that's required right now and adds lot of new issues.

given that we have predefined internal names, the solution is now clear: bootloader_T2T1.bin bootloader_T2B1.bin
