[issue43908] array.array should remain immutable

"TPFLAGS" stands for "type flags". So IMO adding "TYPE" suffix is redundant. If tomorrow, we want to add a flag for immutable instance, we can add a new Py_TPFLAGS_IMMUTABLE_INSTANCE flag.

On the other side, TYPE suffix is consistent with other flags :-)

/* Set if the type object is dynamically allocated */
#define Py_TPFLAGS_HEAPTYPE (1UL << 9)

/* Set if the type allows subclassing */
#define Py_TPFLAGS_BASETYPE (1UL << 10)
