gh-149044: Implement PEP 820 – PySlot: Unified slot system for the C API (GH-149055)

# This file lists all PySlot values
# This should only be used as input to Tools/build/generate_slots.py,
# its format can change at any time (e.g. we can switch to slots.csv)

# Entries:
# name: name of the slot
# kind:
# - 'type', 'mod': slots to create a particular kind of object
# - 'slot': special slots applicable to any kind of object
# - 'compat': old IDs that need to be resolved
# dtype: data type (tag for the union of sl_ptr, sl_size, etc.)
# equivalents: for 'compat' slots; the slots to resolve to
# is_type_field: slot that corresponds to a field in the type object (or in
#   an array like PyNumberMethods).
# functype: C function type, where needed
# duplicates, nulls: How to handle common "problems" -- duplicate slots with
#   the same ID, and NULL pointers, respectively
#   - 'allow': not a problem for this slot
#   - 'deprecated': issue a deprecation warning. Don't use for new slots.
#      (typically, the problem was disallowed in docs, but allowed in practice)
#   - 'reject': raise error
#   The default for duplicate slots is 'reject'
#   The default for NULLs is 'reject' for pointer slots; 'allow' for
#       non-pointer ones
# must_be_static: true if slot needs the PySlot_STATIC flag (in PySlot struct)
