Reorganise Matomo 4 updates for better performance #16284

For better performance we should combine as many queries into one ALTER table statement where possible. Technically there are also 2 drop user columns that could be combined but this table will be fast anyway and executing them individually may be better.

technically could also add all add columns and drop columns for each table together but not sure how much this impacts performance but would potentially make it quite a bit more difficult to implement maybe.

Any other thoughts?
