[Lldb-commits] [lldb] [lldb][lldb-dap] explicitly set the expr as an alias for expression. (PR #134562)

dap console does not recognise `expr` as a command because it is not explicitly set.

It works fine in normal lldb because it is gotten from approximate match which is not available in the SBAPI
