[SYCL][CI][diagnostic] Capture adapter-UAF crash stack via cdb
The UR leak-check run confirmed the use-after-free reproduces (both tests crash
with SEH 0xC0000005 mid-test), but gtest swallows the SEH and prints no stack,
and the teardown leak dump is partly crash debris (SEH skips the crashing test's
local destructors). To get the actual fault stack, run the single crashing test
(SubDevices.BuildProgramForSubSubDevices) under the Windows debugger:
cdb -g -G -c ".symfix; .reload; sxe av; g; r; kP 200; ~*kP; !analyze -v; q"
EXE --gtest_filter=... --gtest_catch_exceptions=0
--gtest_catch_exceptions=0 lets the access violation reach cdb instead of being
swallowed; sxe av breaks at the faulting instruction; the return addresses on
the stack name the call_nocheck / ~Managed caller even when RIP=0. cdb ships
with the Windows SDK Debuggers component; the step locates cdb.exe, is
best-effort, tolerates the crash, and uploads the log as adapter_uaf_crash_log.
