Fix: preserve parentheses around output section VMA

[deepakshirkem]

Problem

Fixes #338

Fix

Call setParen() on the VMA expression when parentheses are detected:

if (consume("(")) {
  if (!readOutputSectTypeAndPermissions(Prologue, peek())) {
    Prologue.OutputSectionVMA = readExpr();
    Prologue.OutputSectionVMA->setParen();  // ← added
  }
  expect(")");
}

Testing

Added a lit test that verifies parentheses are preserved in the plugin output.

Hi @quic-seaswara, Apologies for the build failure. The issue was misleading indentation setParen() was not properly enclosed in braces with the preceding if statement. This has been fixed and the build has been verified locally.

Could you please re-run the pipeline?

Thank you ::))
