refactor(compiler): element.startSourceSpan is required (#38581)

Browse Source 
Previously, the `startSourceSpan` property could be null
but in reality it is always well defined - except for a legacy
case in the old i18n extraction/merging code, where the
typings for source-spans are already being undermined.

Making this property non-null, simplifies code elsewhere
in the project.
