Import the v4l2-isp.h header from the Linux kernel version v6.19-rc1 at
revision e36dbd1cf3df ("media: uapi: Introduce V4L2 generic ISP types").
Create the include/linux/media/ directory so that header files exported
from the kernel which include this file do not need to be adjusted when
imported in libcamera.

Import stddef.h from the Linux kernel sources v6.19-rc1 at revision
c2a756891bb4 ("uapi: wrap compiler_types.h in an ifdef instead of the
implicit strip")
The stddef.h header is imported to provide the __counted_by() symbol
which is not available in the header version shipped with, in example,
Debian 12. __counted_by() will be used by the v4l2-isp.h header which
will be imported next.

When given a relative path to the kernel git tree,
update-kernel-headers.sh fails to execute the headers_install.sh script
from the kernel sources. Fix it by turning the kernel directory into an
absolute path.

When operating on a git worktree, the Linux kernel directory contains a
.git file, not a .git directory. Relax the git tree check to support
both.

The intel-ipu3.h header has moved in the v5.14 kernel. Update the kernel
headers update script accordingly.
While at it, add a missing directory separator to fix a failure when the
path to the kernel tree doesn't end with a /.

Add a script to update the local copy of kernel headers (in
include/linux/) from a Linux kernel git tree. The script handles header
installation, manual processing of the IPU3 header that is still in
staging, and update of the README file.
