Fix ArgsAsWritten being null for ConceptSpecializationExpr in certain
circumstances when parsing ASTs

ASTStmtWriter::VisitConceptSpecializationExpr specifically expects
getTemplateArgsAsWritten() to return true, which it wasn't when parsed
by ASTContext.cpp in certain edge cases.

Fixes: #61486

(cherry picked from commit 1f48a1fce23551cc24f5b598af5994f5cfc6b6d0)
