Victor Stinner 6e7738bb5e gh-158585: Fix _PyBytes_Resize() if hash value is already computed (#158589) ...

_PyBytes_Resize() now creates a new bytes object if the hash value
was already computed.

bytes_resize_inplace() no longer sets the hash value to -1, since
this function must not be called if the hash value was already
computed.

Add tests on PyUnicode_Resize().
