xen,xen-tools: update xen to new releases

Update the SHA in recipes for xen and xen-tools to use the latest releases;
update xen 4.14 to xen 4.14.3 release, update xen 4.15 to 4.15.1 release, and
xen 4.16 to the current master version.

Add a comment to each recipe indicating which version of Xen is used in recipe.

Do not apply patches that have been merged/solved in Xen and remove patch files
not needed anymore.

Create a test package to pack new tests introduced in 4.16.

Add a depencency to util-linux-prlimit, as the xen 4.16 x86 requires prlimit,
without this boot of dom0 fails.

-Subject: [PATCH] x86: make hypervisor build with gcc11
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Gcc 11 looks to make incorrect assumptions about valid ranges that
-pointers may be used for addressing when they are derived from e.g. a
-plain constant. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100680.
-
-Utilize RELOC_HIDE() to work around the issue, which for x86 manifests
-in at least
-- mpparse.c:efi_check_config(),
-- tboot.c:tboot_probe(),
-- tboot.c:tboot_gen_frametable_integrity(),
-- x86_emulate.c:x86_emulate() (at -O2 only).
-The last case is particularly odd not just because it only triggers at
-higher optimization levels, but also because it only affects one of at
-least three similar constructs. Various "note" diagnostics claim the
-valid index range to be [0, 2⁶³-1].
