It's easy enough to disable the lldb-server build. The lldb-server unit
tests already have logic to disable them if we don't build, so this just
makes it even.

This diff modifies the LLDB server return codes to more accurately reflect usage
error paths. Specifically we always propagate the return codes from the main
entrypoints into GDB remote LLDB server, and platform LLDB server. This way, the
top-level caller of LLDB server will be able to correctly check whether the
executable exited with or without an error.
We additionally modify and extend the associated shell unit tests to expect
nonzero return codes on error conditions.
Test Plan:
LLDB tests pass:
```
ninja check-lldb
```

It seems that TestErrorMessages.test is failing on the standalone + Xcode builds
as lldb-server executable can't be found by lit's default PATH search. I assume
invoking lldb-server via a lit substitution gets this working again as
everything else is working, so that's what this patch is doing.
I had to add the lldb-server substitution as the test seems lldb-server specific
and we don't want it to default to debugserver on Darwin.
Using a substitution also seems in general like a good idea so that the commands
lit is printing on failure are using the full path to lldb-server and can be
re-run in a terminal.

The existing help text was very terse and was missing several important
options. In the new version, I add a short description of each option
and a slightly longer description of the tool as a whole.
The new option list does not include undocumented no-op options:
--debug and --verbose. It also does not include undocumented short
aliases for long options, with two exceptions: -h, because it's
well-known; and -S (--setsid), as it's used in one test. Using these
options will now produce an error. I believe that is acceptable as users
aren't generally invoking lldb-server directly, and the only way to
learn about the short aliases was by looking at the source.
