Ayaz Hafiz 11f7e275e6 feat(compiler): type TemplateAst values as ASTWithSource (#35892)
TemplateAst values are currently typed as the base class AST, but they
are actually constructed with ASTWithSource. Type them as such, because
ASTWithSource gives more information about the consumed expression AST
to downstream customers (namely, the expression AST source).
