Host apexes are passed to microdroid via the payload composite image.
The payload composite image can be created by either
mk_payload_signature/mk_cdisk or mk_payload.
For now, microdroid expects two APEXes from the host:
- com.android.adbd
- com.android.sdkext
The exact set of host apexes for microdroid is TBD. The current set is
only for demonstration.

All files to run microdroid is now included to the com.android.virt
APEX:
- super image
- boot images
- vbmeta images
- bootloader
- uboot_env image
- cdisk json config
Also the documentation README.md and microdroid host tests are updated
too.

The signing is effectively no op for now because nothing verifies the
bootloader. However, in the end, the pKVM firmware will verify the
bootloader and use the vbmeta footer appended to it.

mk_cdisk is a tool to create a composite disk image. It can be used to
create other kinds of composite disks as well as os_composite.os which
was created by assemble_cvd before.
For example, if we want to pass host apexes to microdroid we can pass
them via a composite disk referencing host apex files.

assemble_cvd needs crosvm, but /apex/com.android.virt/bin is not in
$PATH. This adds the directory to $PATH so assemble_cvd can be happy.

The following system properties are forcibly set to make adbd function.
ro.apex.updatable=true : otherwise, apexd doesn't activate critical
APEXes like the runtime APEX
ro.adb.secure=0 : to bypass the adb authentication
ro.debuggable=1 : to be able to use ro.adb.secure=0
This change also updates README.md file for the instruction to use adb.
