e2f63a07b2 hv: Improve VM emulation for tracer 
Adds support for up to 64-byte ops and more SIMD/paired operations.
This is good enough to trace a lot of GPU VM address space.

302a9ec4c0 m1n1.hv: Add BYPASS trace mode 
Forces SW mapping but does not do any hooking. This can be useful for

780c0644d4 display: Fix HPD detection bug

df53f16f76 m1n1.hv: Copy /chosen/memory-map/preoslog if it exists 
preoslog was added in macos 12.3 and seems to contain iBootStage1 log
output. Since macos 12.3 accesses it it has to be copied to after the
guest image.

set_display_device difference is taken from macOS trace on t6001.

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
