[lldb] Pass important options to dsymForUUID (#72669)

On macOS, we usually use the DebugSymbols framework to find dSYMs, but
we have a few places (including crashlog.py) that calls out directly to
dsymForUUID. Currently, this invocation is missing two important
options:

* `--ignoreNegativeCache`: Poor network connectivity or lack of VPN can
lead to a negative cache hit. Avoiding those issues is worth the penalty
of skipping these caches.
* `--copyExecutable`: Ensure we copy the executable as it might not be
available at its original location.
