[issue46881] Statically allocate and initialize the latin1 characters.

[Kumar Aditya]

New submission from Kumar Aditya :

Statically allocate and initialize the latin1 characters. This *should* make 
iterating over a ascii strings faster as it avoids an atomic read in 
PyInterpreterState_GET() to get unicode state in get_latin1_char, makes 
get_latin1_char branchless and can be used in deepfreeze for identifiers.
