  [lldb] Disable delayed-breakpoints by default for lldb 23

https://github.com/llvm/llvm-project/pull/192971 added a delayed
breakpoints feature, which delays sending the breakpoint management
packets until we actually continue the process. The feature itself
is working, but it has made it easier to hit a bunch of pre-existing
issues handling reads and writes around breakpoints.

https://github.com/llvm/llvm-project/issues/217359,
https://github.com/llvm/llvm-project/issues/217840,
https://github.com/llvm/llvm-project/issues/217359,
https://github.com/llvm/llvm-project/issues/205120 and
https://github.com/llvm/llvm-project/issues/202672
(reported by a downstream project as https://github.com/llvm/llvm-project/issues/216000)

These are all now fixed on the main branch, but it would
be a large backport to bring them over. Whereas this change
is a single line.

delayed-breakpoints is purely a performance improvement,
and users can opt into it by changing the setting.

This leaves the underlying bugs in place, but those
bugs are not regressions in 23. They have been present
for many years.
