[lldb-dap] Rename enableDisplayExtendedBacktrace (llvm#109521)

The `enable` prefix is a filler word which adds no additional
information. Rename the setting to `displayExtendedBacktrace`

Given that this setting was only introduced a month ago, and that there
has not been any release since then, I assume that usage is still rather
low. As such, it should be fine to not provide backwards-compatibility
workarounds.

(cherry picked from commit 19ecded)
