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.

overlay data needs to be removed from buildroot target directory

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:

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.
