3.13 adds C macros/functions/types without the `Py`/`_Py` prefix

[encukou]

3.13 newly defines the following unprefixed functions/macros/types via Python.h. They should probably be hidden:

• [x] uop_get_target in Include/cpython/optimizer.h:67
• [x] uop_get_exit_index in Include/cpython/optimizer.h:73
• [x] uop_get_jump_target in Include/cpython/optimizer.h:79
• [x] uop_get_error_target in Include/cpython/optimizer.h:85
• [x] BLOOM_FILTER_WORDS in Include/cpython/optimizer.h
• [x] UOP_FORMAT_TARGET in Include/cpython/optimizer.h
• [x] UOP_FORMAT_EXIT in Include/cpython/optimizer.h
• [x] UOP_FORMAT_JUMP in Include/cpython/optimizer.h
• [x] UOP_FORMAT_UNUSED in Include/cpython/optimizer.h
• [x] struct _bloom_filter in Include/cpython/optimizer.h:19
• [x] struct _exit_data in Include/cpython/optimizer.h:91
• [x] optimize_func in Include/cpython/optimizer.h:112
• [ ] CO_NO_MONITORING_EVENTS in Include/cpython/code.h:192

Can't we move most of Include/cpython/optimizer.h contents to the internal C API? Is there a reason to expose it? I mean, the private functions (named prefixed by _Py).
