  [Flang] Fix statement-function shadowing to avoid false unresolved-symbol internal error (#189360)

When a statement function shadows a host-associated internal procedure
name, HandleStmtFunction creates a local symbol but leaves name.symbol
pointing to the host SubprogramNameDetails.

Because of that stale pointer, AnalyzeStmtFunctionStmt exits early (it
expects SubprogramDetails), so the RHS is never resolved and flang emits
a false `internal error: "Internal: no symbol found".` Clearing
name.symbol after creating the local shadow symbol lets it re-resolve
correctly and fixes the issue.
