  [lldb][Windows] Don't let the inferior inherit the --pipe handle (#207024)

`lldb-server` writes its listening socket id to the `--pipe` handle and
then closes it. The parent process that spawned it reads the pipe until
EOF purely as a synchronization point (`"the server is now listening"`).

On Windows the inferior is launched with `bInheritHandles=TRUE` (it
needs the ConPTY handles), so it also inherited the pipe's write end.
That kept the write end open after `lldb-server` closed its own handle,
so the parent never saw EOF: it blocked until its read timeout and the
client's connection handshake timed out first.

This patch clears `HANDLE_FLAG_INHERIT` on the `--pipe` handle so the
inferior cannot keep the write end open, while leaving it valid for
lldb-server's own use.
