[lldb][test] Disable a bunch of flakey lldb-dap tests

These, or parts of these, are all failing every so often on Linaro's
build bots with:
    raise ValueError(desc)
ValueError: no response for "disconnect"

Sorry to use a global disable here but this is happening too often
and spamming unrelated PRs.

I think it's the same issue as #137660.
