4575b35479 rust: Initial Rust-based EFI FAT32 chainloader 
This code is gated behind the CHAINLOADING define. To build a
release-style m1n1 with chainloading for use with the installer
or kmutil, use:

make CHAINLOADING=1 RELEASE=1

To tell m1n1 to chainload another binary, use this var payload:

chainload=<ESP partition UUID>;<file path>

e.g.

chainload=a17b7e46-e950-bb4f-bc82-8ab1047a058e;m1n1/m1n1.bin

Closes: #154
