Support distinguish if function is generated from namspace/enum syntax · Pull Request !1012 · OpenHarmony/arkcompiler_ets_frontend

### Description:
In es2abc, namespace/module/enum syntax will be transformed to `variable + function call expression`, like tsc, and then emit bytecode. eg:

```ts
// original code
namespace A {
  let a = 1;
}

// transformed code
var A;
(function (A) {
    let a = 1;
})(A || (A = {}));
```

The corresponding ast before/after transform is like:
```
// before
TSModuleDeclaration
    TSModuleBlock
        VariableDeclaration

// after
VariableDeclaration
ExpressionStatement
    CallExpression
        FunctionExpression
            ScriptFunction // the ast node will emit corresponding instruction: definefunc 
    LogicalExpression
        Identifier
        AssignmentExpression
            Identifier
            ObjectExpression
```

In order to support AOT type infer for namespace/enum, \
we bind typeindex -1 for function annotation to represent it's generated from namespace/module syntax, \
and bind typeindex -2 to represent it's generated from enum syntax.
