dev-debug/hotspot: new package, add 1.5.1_p20250907, 9999

Take a snapshot as upstream releases seem infrequent and we'd have to backport a few patches if using the last release, and I already did the dep work for master. Based on the ebuild from ::kdab-overlay [0]. [0] 640bf73ef2/dev-util/hotspot/hotspot-1.5.1.ebuild Closes: https://bugs.gentoo.org/624062 Signed-off-by: Sam James <sam@gentoo.org>
