The vendor_boot.img now has fstab file in it. It currently mounts the
system.img to /system, but eventually we will use the dynamic partitions
in super.img.
A few more essential kernel commandline params are added. Eventually,
these androidboot.* parameters will be given via /proc/bootconfig.

Test: build microdroid-* modules. push microdroid-boot-5.10.img as
boot.img, microdroid-vendor-boot-5.10.img as vendor_boot.img,
micrdroid.img as super.img.
Run assemble_cvd on the device.
Push microdroid-uboot_env.img as uboot_env.img
Run crosvm with the generated composite image. VM goes through the
bootloader, kernel, first stage init, and then second stage init.

The environment partition can control the behavior of the bootloader.
Therefore it shouldn't be dynamically created on the device.

Contexts files, plat_sepolicy.cil, and 10000.0.cil are needed to boot.
This adds those files to microdroid. But cil files are temporary and
only for testing. We'll need to migrate real cil files to Android.bp.

Test: boot microdroid

This adds a minimized init.rc and services to microdroid, so microdroid
can boot and adb can work.

Test: boot with manually added selinux stuffs and apexd session patch

These lists are based on rootdir contents. A little more shrinked.

It consists of
* common kernel modules for virtual devices
* a dummy dtb image

This file is a simple copy of system/sepolicy/private/file_contexts to
support contexts for microdroid.img. It contains unnecessary entries,
but we'll leave it for now and clean up after enough experiment.

microdroid is a minimal Linux image that we will use in VMs. Instead of
inventing a whole new Linux image from scratch, we design microdroid as
a stripped down version of the generic Android system image (GSI).

Test: m microdroid
Test: no runtime test. This isn't mountable yet.
