Revert "wasm: Specify event targets by CSS selectors; Support emsdk >= 1.39.5"

Browse Source 
This reverts commit c6da278271.

This was a 5.15-only change which should not go into 5.14
since it raises the minimum supported emsdk version.

Task-number: QTBUG-83098
Change-Id: I9e15952803f9dfff89b5b4e9caeff5c03dabca27
