fix: addDebugInfo before convertExpression

[XMadrid]

Fixes #2833 .

add debugLocation before convertExpression. For code snippet:

function add(a: i32, b: i32): i32 {
  return a + b;
}

add(1, 2);

Before this PR, we emit:

addDebugLocation(drop, line = 5, column = 2);       // In there, we should emit `call` instruction
addDebugLocation(drop, line = 5, column = 2); 

With this PR, we emit:

addDebugLocation(call, line = 5, column = 2);      
addDebugLocation(drop, line = 5, column = 2);

I think we can emit debug location for both outside expr and inside expr.
