aconfig_device_paths uses `include_str!` to include a text file containing comma-separated strings with each partition aconfig file. The lib does not handle the escaped newlines and quotation marks. Adds proper handling. Test: cargo t && m -j120 && acloud create --local-image && adb shell aflags list Bug: 340514768 Change-Id: I75214bf02dd962d8291f1654ade8cbce1cda9fde
