Property '__timer' is a reserved C++ word, consider renaming [compiler]

minimal reproduction project: https://git.qt.io/mikio_hirai/reserved_words_qds_qmltc#

Branch is master and the commit is 454e492d814f644c1fa78e1991765fcee1c63d33. If you want to quickly see the error, configure and build the project with Desktop Qt 6.8.1 MSVC2022 64-bit kit.

<Issue>
QDS-generated EventListSimulator.qml contains "_timer" and "_timerChanged" which are reserved C++ words, causing QMLTC errors below while app compilation:

Error: C:/Users/81808/Downloads/ReservedWordsInEventSimulator/ReservedWordsInEventSimulator/EventListSimulator.qml:8:1: Property '__timer' is a reserved C++ word, consider renaming [compiler]
Error: C:/Users/81808/Downloads/ReservedWordsInEventSimulator/ReservedWordsInEventSimulator/EventListSimulator.qml:8:1: Method '__timerChanged' is a reserved C++ word, consider renaming [compiler] 

<How to reproduce>
1. Create a project in QDS 4.6.2.

2. Export the project by File > Export Project > Enable CMake Generator

3. Open the exported project with Qt Creator

4. Add ENABLE_TYPE_COMPILER to qt6_add_qml_module() in https://git.qt.io/mikio_hirai/reserved_words_qds_qmltc/-/blob/master/ReservedWordsInEventSimulator/CMakeLists.txt?ref_type=heads#L20.

5. Configure and build the project

<Fix>
Rename them to non-reserved words in C++.
