Autogen: AUTO*_EXECUTABLE: add support for per-config values

* Per-config values were added to `AUTO*_EXECUTABLE`.
* Dependency order was refactored for `cmake_autogen` and `cmake_autorcc` to
  avoid unnecessary rebuilds.
* A new parameter was added for `cmake_autogen` and `cmake_autorcc` to specify the config name of the `auto*_executable` to be used.
* The timestamp target was split into three targets for per-config to avoid redundant `mocs_compilation` builds.
* Per-config `DEP_FILE_RULE_NAME` values were added to `AutogenInfo.json` for `CMAKE_CROSS_CONFIG` usage.
* Some functions were refactored to avoid code duplication.

Fixes: #20074
