Implement kexec

To support ramdump of VMs, implement a kexec binary and add it to
Microdroid. The binary will be used to preload the kernel and the init
ramdisk that the system will boot into when a kernel panic occurs.

The binary is very minimal. It has much less functionalities than the
upstream kexec-tools. It has a different cmdline interface, and is just
a thin wrapper around the kexec_file_load syscall. It supports loading
the kernel and the ramdisk only for the exec-on-crash use case.

Bug: 237380224
Test: run kexec on Microdroid
