[Backtracing] Support specifying a hard-coded path for swift-backtrace.
...
Add a way to disable dynamic lookup of the backtracer path, for situations
where a hard-coded path makes more sense.

[Backtracing] Add an option to output to stderr.
...
In CI, it would be better if the backtraces went to stderr rather than
stdout, so provide an option for that.

[Backtracing] Add control over symbol caching.
...
Some symbolication frameworks have a symbol cache; we probably don't want
to use that for test cases, to avoid running into problems where the cache
holds stale information.

[Backtracing][Runtime] Disable backtraces for setuid binaries.
...
We really, really shouldn't be running the external backtracer for setuid
binaries. It's just too dangerous.
So don't do that. And if someone tries to force us, emit a warning.
