refactor(language-service): Remove redudant 'TemplateInfo' type (#32250)

Browse Source 
The TemplateInfo type is an extension of AstResult, but it is not
necessary at all. Instead, improve the current interface for AstResult
by removing all optional fileds and include the TemplateSource in
AstResult instead.
