Prevent overly deep build dir hierarchy on Windows

On Windows, building Qt with Ninja Multi-Config failed in a reasonably named build dir. The reason for that is our deep build dir hierarchy, created with add_subdirectory, and long target names like QNetworkListManagerNetworkInformationBackend within that hierarchy. Rename said target to QNLMNIBackend, and set AUTOGEN_BUILD_DIR to a short string that does not repeat the target name. Pick-to: 6.1 Fixes: QTBUG-94211 Change-Id: Iea6fee012fa46d9bfb01142b60e6cb5273893c50 Reviewed-by: Alexandru Croitor <[email protected]>
