repr() of a symtable.Symbol raised TypeError under -X lazy_imports=all. _flags and _scopes_value_to_name were built from globals(), which holds unresolved lazy import objects for the names imported from _symtable.

• Build both tables from _symtable instead. The names and order are the same, so repr() output without lazy imports is unchanged
• Remove test_symtable from Lib/test/lazy_imports_all_exclude.txt, so the lazy imports CI job now runs it
• Add test_symbol_repr_lazy_imports, which checks repr() in a subprocess with -X lazy_imports=all

Testing: test_symtable passes normally and with -X lazy_imports=all (also with --fast-ci). The new test fails without the fix.

Fixes #160810

Just a small nitpick for xref purposes
