### What changes were proposed in this pull request? It is very confusing that the default save mode is different between the internal implementation of a Data source. The reason that we had to have saveModeForDSV2 was that there was no easy way to check the existence of a Table in DataSource v2. Now, we have catalogs for that. Therefore we should be able to remove the different save modes. We also have a plan forward for `save`, where we can't really check the existence of a table, and therefore create one. That will come in a future PR. ### Why are the changes needed? Because it is confusing that the internal implementation of a data source (which is generally non-obvious to users) decides which default save mode is used within Spark. ### Does this PR introduce any user-facing change? It changes the default save mode for V2 Tables in the DataFrameWriter APIs ### How was this patch tested? Existing tests Closes #25876 from brkyvz/removeSM.
