[3.14] gh-129824: fix data races in subinterpreters under TSAN (GH-135794) (#136266)

gh-129824: fix data races in subinterpreters under TSAN (GH-135794)

This fixes the data races in typeobject.c in subinterpreters under free-threading. The type flags and slots are only modified in the main interpreter as all static types are first initialised in main interpreter.
(cherry picked from commit b582d751b4968d4534fdb7894e50713676789b2f)
