Previously this used `var` as both an lldb command and variable in the
source to validate the behavior of the 'auto' repl mode. However, `var`
seems to occasionally fail in the CI test when attempting to print some
c++ types. Instead switch the command and variable name to `list` which
should not run the dynamic variable formatting code for c++ objects.
This should fix#116041.
Update lldb-dap so if the user just presses return, which sends an empty
expression, it re-evaluates the most recent non-empty
expression/command. Also udpated test to test this case.
Rename lldb-vscode to lldb-dap. This change is largely mechanical. The
following substitutions cover the majority of the changes in this
commit:
s/VSCODE/DAP/
s/VSCode/DAP/
s/vscode/dap/
