Remove redundant pycore_optimizer.h includes ( #143184 )
...
`pycore_optimizer.h` was included redundantly in
Objects/frameobject.c and Python/instrumentation.c.
Both includes are unnecessary and can be safely removed.
No functional change.

These super instructions need many special cases in the interpreter, specializer, and JIT. It's best we convert them to normal instructions.

...
This makes generator frame state transitions atomic in the free
threading build, which avoids segfaults when trying to execute
a generator from multiple threads concurrently.
There are still a few operations that aren't thread-safe and may crash
if performed concurrently on the same generator/coroutine:
* Accessing gi_yieldfrom/cr_await/ag_await
* Accessing gi_frame/cr_frame/ag_frame
* Async generator operations
