Move adding try/catch blocks in evaluation from SDK to dwds

Currently, expression compiler wraps the compiled JS expression in a try/catch block, which does not work well with VMService.evaluate() calls using scope - dwds needs to strip the try/catch to be able to call the function that is the JS expression inside the block.

Suggestion: either remove the wrapper or make dwds decide when it is needed.

Note: we should make sure errors are reported cleanly.

Start by tracing the expression compiler's try/catch wrapper and DWDS handling of VMService.evaluate() calls using scope. Compare where the wrapper is added and where DWDS needs to remove it, then verify that evaluation errors are reported cleanly and that scoped calls can invoke the JavaScript expression function.
