Add a patch for QGIS 4.0-way of writing project entries #4359
Description
QGIS 4.0 changed how project entries are written (and read) from/to project files. In order to properly read MM-related settings (like map sketching, photo sketching, tracking ...), we need to get the patch and apply it on our end (patch in vcpkg).
Originally introduced here qgis/QGIS#60855 and then reapplied here qgis/QGIS#62349

As for testing, we need to verify that the app follows MM-related settings in projects created with QGIS 4.x.
Verification / acceptance criteria:
- Projects created with QGIS 4.x can be opened on the mobile app without errors + MM-related settings are preserved as set in the plugin (e.g. enabled position tracking)
- Projects created with QGIS 3.x can be opened on the mobile app without errors + MM-related settings are preserved as set in the plugin (e.g. enabled position tracking)
