Add the framework to build kernel config files from trees
of kernel fragments.
If no fragment directory is found for the requested kernel
version and architecture then revert to looking for a whole
prebuilt kernel config file instead.

This patch is update version for [1] as kernel
upgrad to v4.19.
It derives from [2] which has accept by kernel
community after v4.20. Modifacation has been done
to make it be able to enable memory hotplug using
probe method as it originally aims to using acpi.
Also some corresponding configurations in kernel
config are opened.

`build-kernel_test.sh` builds the kernel when there are changes
of it in a PR and then runs the whole CI tests. Now we are running
all CI tests on all changes[1] (not only when there is a kernel change).
This is making the CI to run all tests twice when there is a change
in the kernel, so we need to remove the script.

As memory hotplug for arm64 by acpi is not ready on qemu, we choose
"probe" instead. You can refer to [1] to get more infomation about
"probe". The process of memory hotplug by "probe" in kata lies below:
firstly, add memory in qemu qmp; secondly, echo the start phyical address
of that memory to /sys/devices/system/memory/probe, which will be done
through kata-agent; thirdly, excute online op, then this newly added
memory is capable to be used.
All functions in this patch will be called after "echo" op. It can be
divided into two parts:
1. create page table for that memory;
2. add that memory to memblock.
In this patch, NUMA must be turned off for not all arm64 machine supports
NUMA.
As the newly added memory should be placed from 2T to 6T which is decided
in qemu and phyical address and virtual address will be one-one mapping
when create pgd for that memory, we must config ARM64_VA_BITS as 48.
Also some configs should be turned on, especially "ARCH_MEMORY_PROBE".
We have tested this patch integrated with another patch which performed
that echo op. It works well when using "-m" in command line when start a
kata-container on aarch64 machine.
This patch derived from Maciej Bielski. You can refer to [2] to get full
infomation about it.
