Overflows happened silently in array.array setters for 'e', 'f' and 'Zf' format types

Bug report

Bug description:

Consider this:

>>> import array
>>> a = array.array('e', [123])
>>> a[0] = 123456
Traceback (most recent call last):
  File "<python-input-2>", line 1, in <module>
    a[0] = 123456
    ~^^^
OverflowError: float too large to pack with e format
>>> a = array.array('f', [123])
>>> a[0] = 1e70  # no OverflowError
>>> a
array('f', [inf])
>>> a = array.array('Zf', [123])
>>> a[0] = 1e70j  # no OverflowError
>>> a
array('Zf', [infj])
>>> import struct
>>> struct.pack('f', 1e70)
Traceback (most recent call last):
  File "<python-input-7>", line 1, in <module>
    struct.pack('f', 1e70)
    ~~~~~~~~~~~^^^^^^^^^^^
OverflowError: float too large to pack with f format
>>> struct.pack('>Zf', 1e70j)
Traceback (most recent call last):
  File "<python-input-13>", line 1, in <module>
    struct.pack('>Zf', 1e70j)
    ~~~~~~~~~~~^^^^^^^^^^^^^^
OverflowError: float too large to pack with f format

(BTW, f_setitem() suffers from same issue as https://github.com/python/cpython/issues/156864.)

Maybe it's a feature and array() should behave differently wrt the struct module. In either case, this behavior looks inconsistent. If we consider cases for 'f'/'Zf' types being correct - we should clear exceptions also for 'e' type code.

Commencez par les setters de array.array pour les formats 'e', 'f' et 'Zf', puis comparez leur comportement en cas d’overflow avec celui de struct.pack, comme indiqué dans le rapport. Examinez les PRs liés et les issues associées avant de déterminer la cohérence attendue ; le travail est terminé lorsque le comportement sélectionné est implémenté et couvert pour ces types de format.
