[CIR][CodeGen] Support return in TryOp

[bruteforceboy]

This PR adds support for returns inside of a TryOp, for example:

void foo() {
  int r = 1;
  try {
    return;
    ++r;
  } catch (...) {
  }
}

Currently, it fails during the CodeGen with:

error: 'cir.return' op expects parent op to be one of 'cir.func, cir.scope, cir.if, cir.switch, cir.do, cir.while, cir.for, cir.case'

were TryOp's omitted on purpose?

wasn't updated properly when introduced, thanks for spotting that
