sw5100.kasan_swtags: Enable stacktrace collection for KASAN builds
Stackdepot is needed to let KASAN capture stacktraces for
paths that allocate and free memory. These stacktraces are
valuable to developers when using KASAN, so ensure that the
kernel build can build a kernel image that enables stackdepot
for KASAN builds.
This has the added benefit of not having to repackage the vendor_boot
image in the platform build to enable stackdepot, as KASAN kernel
builds will have stackdepot enabled by default.
