tests/migration/aarch64: Speed up the aarch64 migration test

The migration tests spend a lot of time waiting for a sign of live
of the guest on the serial console. The aarch64 migration code only
outputs "B"s every couple of seconds (at least it takes more than 4
seconds between each characeter on my x86 laptop). There are a lot
of migration tests, and if each test that checks for a successful
migration waits for these characters before and after migration, the
wait time sums up to multiple minutes! Let's use a shorter delay to
speed things up.

While we're at it, also remove a superfluous masking with 0xff - we're
reading and storing bytes, so the upper bits of the register do not
matter anyway.

With these changes, the test runs twice as fast on my laptop, decreasing
the total run time from approx. 8 minutes to only 4 minutes!

tests: Add migration test for aarch64

This patch adds migration test support for aarch64. The test code, which
implements the same functionality as x86, is booted as a kernel in qemu.
Here are the design choices we make for aarch64:

* We choose this -kernel approach because aarch64 QEMU doesn't provide a
built-in fw like x86 does. So instead of relying on a boot loader, we
use -kernel approach for aarch64.
* The serial output is sent to PL011 directly.
* The physical memory base for mach-virt machine is 0x40000000. We change
the start_address and end_address for aarch64.

In addition to providing the binary, this patch also includes the source
code and the build script in tests/migration/aarch64. So users can change
the source and/or re-compile the binary as they wish.
