Remove all unused build-scripts and other files, they are not used, not
tested, so it doesn't make sense to keep them, if any similar
functionality is needed in future, we can add a well-tested script in
future.

Move all common config to common.base and override the necessary

Signed-off-by: Jagdish Gediya <jagdish.gediya@arm.com>

It doesn't make sense to keep the configuration for unused platforms
as the configs are quite old, and this project doesn't follow(rebase) any such
platform support regularly.

This is necessary to keep code elegant, to refactor the configuration.

Create dedicated functions for each task while modifying distro image
with custom kernel and initrd.

Also, change the directory name for uefi/distro artifacts to match it
with ci tests.

This refactoring is expected to be useful while adding support for the
new distro boot support in future with minimal modification.

macvtap along with FVP tap interface allows the host booted on FVP
and realm guests booted on host to reach outside world over network.

This will be required to run attestation demo where keybroker server
or verifier would be running outside the local network.

Also, remove ssh connection from host to guest test as it doesn't work
as libvirt on host where FVP is run doesn't provide any route and
blocks traffic.

Replace buildroot prompt from '#' to $USER@buildroot:~# by adding
/etc/profile file to rootfs overlay, this needs to be done as '#'
appears in kernel logs also which results into CI assuming the boot is
complete, it tries to run further comands and fails.

profile file is copied from buildroot code, and PS1 variable is modified
on top of default file available in buildroot.

Add support to run individual commands like clean/build/package
with build-stack.sh script.

Generally all target does build and doesn't clean the project. Cleaning
all the components and building them again takes lot of time so don't
clean the components with all target, while running all target if there
is an error for the single component, running all again will start fresh
build and makes debugging take unnecessary long time, fresh checkout are
anyway clean so should be fine to build without cleaning.

This will also be useful to package everything without taking long time
when single component is modified, in such case, just clean the single
component and run the all target on all the components.

If full cleaning is required then clean target can be run with build-stack.sh
script.

Also, don't run build command by default when no command is specified.

In order for the build to work under ubuntu 24.04 the following changes
are required:

- Currently ACPICA has not been updated to deal with new warning types
introduced in the compiler version distributed with ubuntu 24.04. So in order
for these warnings not to be converted to errors the NOWERROR option
has been added to the ACPICA build.

- The latest kernel headers remove a number of symbols currently
required by the TC utility within busybox. in order to resolve
this build error CONFIG_TC has been removed as it is not required
and is recomended as a workaround for this issue here:

Modify build-buildroot.sh to update the kernel, grub and the initrd
in the build. This accelerates build time by removeing the need to
boot the distro and install the packages. The system will do the
following:

1. Download the correct version of the Debian image.
2. Remove the filesystem from the Debian image.
3. Upgrade the kernel within the filesystem.
4. Update the initrd to match the new kernel.
5. Repack the updated filesystem in to the image.
6. Build the update image into the buildroot filesystem.
