  [lldb] Set SO_NOSIGPIPE on platforms that support it (#198044)

On macOS, I've seen instances where debugserver goes down very quickly
after it starts up (less than 100ms). Normally, LLDB is able to detect
when debugserver goes down and report it without bringing down the
entire debug session. However that's not happening here. My best guess
is that debugserver is going down before LLDB is ready to react to it.

To mitigate this scenario, adopt SO_NOSIGPIPE. Note that this mostly
matters for tools that embed liblldb. The LLDB driver ignores all
SIGPIPEs.
