Adding more supported operators to DIL breaks tests in `DWIMPrint` and `lldb-dap`, which shouldn't be simply adjusted for new DIL capabilities. They act as a check for the boundaries of what subset of expressions `DWIMPrint` and `lldb-dap` expect to be evaluated when using `GetValueForVariableExpressionPath` function. With this patch, the caller can now pick a mode that limits the expressions DIL can evaluate, which ensures the expected preexisting behavior. More operators can now be safely added to DIL, which can still be evaluated by DIL when using `frame var` command or the API call with Full mode selected (or not specified at all). DIL will only attempt evaluating expressions that contain operations allowed by a selected mode: - Simple: identifiers, operators: '.' - Legacy: identifiers, integers, operators: '.', '->', '*', '&', '[]' - Full: everything supported by DIL
