This adds new types for setExceptionBreakpoints and adds support for
`supportsExceptionFilterOptions`, which allows exception breakpoints to
set a condition.
While testing this, I noticed that obj-c exception catch breakpoints may
not be working correctly in lldb-dap.
Adding an assert that the 'continue' request succeeds caused a number of
tests to fail. This showed a number of tests that were not specifying if
they should be stopped or not at key points in the test. This is likely
contributing to these tests being flaky since the debugger is not in the
expected state.
Additionally, I spent a little time trying to improve the readability of
the dap_server.py and lldbdap_testcase.py.
This PR changes how we treat the launch sequence in lldb-dap.
- Send the initialized event after we finish handling the initialize
request, rather than after we finish attaching or launching.
- Delay handling the launch and attach request until we have handled
the configurationDone request. The latter is now largely a NO-OP and
only exists to signal lldb-dap that it can handle the launch and
attach requests.
- Delay handling the initial threads requests until we have handled
the launch or attach request.
- Make all attaching and launching synchronous, including when we have
attach or launch commands. This removes the need to synchronize
between the request and event thread.

Refactoring `stackTrace` to perform frame look ups in a more on-demand
fashion to improve overall performance.
Additionally adding additional information to the `exceptionInfo`
request to report exception stacks there instead of merging the
exception stack into the stack trace. The `exceptionInfo` request is
only called if a stop event occurs with `reason='exception'`, which
should mitigate the performance of `SBThread::GetCurrentException`
calls.
Adding unit tests for exception handling and stack trace supporting.
The don't currently work (and they're also not particularly useful,
since all of the remote stuff happens inside lldb).
This saves us from annotating tests one by one.
Rename lldb-vscode to lldb-dap. This change is largely mechanical. The
