std.posix.abort: only trigger breakpoint on Windows if being debugged
Processes should reasonably be able to expect their children to abort
with typical exit codes, rather than a debugger breakpoint signal. This
flag in the PEB is what would be checked by `IsDebuggerPresent` in
kernel32, which is the function you would typically use for this
purpose.
This fixes `test-stack-trace` failures on Windows, as these tests were
expecting exit code 3 to indicate abort.1 files changed, 1 insertions(+), 1 deletions(-)
