Support NVMe and MMC devices

[oldfred]

I would like to add entry to search of Boot_Files_Fat= lines.
/EFI/ubuntu/grub.cfg
Not sure what other distributions use. I have seen /EFI/grub but not then sure now if grub.cfg or other. And each distribution like Mint uses that. Not sure if DISTRIB_ID= would cover other cases or not.

Also need search of newer drives as part of All_Hard_Drives=
/dev/nvme0n1
/dev/mmcblk0

I added search for custom.cfg on FAT in v0.77.

As for NVMe - they are not usually even bootable with legacy BIOS and BIS is only partially useful for EFI anyway. In any case, NVMe supports needs patch from someone who owns this hardware and can test it. I change subject so someone can pick it up for implementation.

NVMe is just another medium on which an OS can be installed. I installed a legacy Windows 10 system on an NVME drive and adjusted the bootinfoscript to detect it. Maybe you can take over my changes. Following the changed script:
bootinfoscript.tar.gz

@oldfred it looks like your diff is not the right diff. When i tried to patch it on the tarball linked by @baedacool it told me
