Renames the streaming merge-append write config to `use-merge-append-for-streaming` in Spark 4.1, and ports the option to the Spark 3.5 and 4.0 modules. When enabled, streaming appends use a merge append instead of a fast append so manifests are merged on commit rather than accumulating as small manifests.

Since the 4.1 change is just a rename that we don't need to worry about compatibility about and the change is fairly small, I included it with the Spark version backports as well. |

This change includes 2 parts:
1.) Rename streaming-merge-append-enabled to use-merge-append-for-streaming for better readability of the conf. This change was just merged and not released so no compatibility issues in changing this config.
2.) After the rename of the config, clean backport of the change from #17347 to Spark 4.0/3.5
